B Y BREAKFAST, EVERYONE KNEW HE WAS GONE. T HEIR glances and whispers followed me to the table, lingered as I reached for food. I chewed and swallowed, though the bread sat like a stone in my stomach. I yearned to be away from the palace; I wanted the air.

I walked to the olive grove, the earth dry beneath my feet. I half- wondered if I was expected to join the boys, now that he was gone. I half- wondered if anyone would notice whether I did. I half-hoped they would. Whip me, I thought.

I could smell the sea. It was everywhere, in my hair, in my clothes, in the sticky damp of my skin. Even here in the grove, amidst the must of leaves and earth, the unwholesome salty decay still found me. My stomach heaved a moment, and I leaned against the scabbed trunk of a tree. The rough bark pricked my forehead, steadying me. I must get away from this smell , I thought.

I walked north, to the palace road, a dusty strip worn smooth by wagon wheels and horses’ hooves. A little beyond the palace yard it divided. One half ran south and west, through grass and rocks and low hills; that was the way I had come, three years ago. The other half twisted northwards, towards Mount Othrys and then beyond, to Mount Pelion. I traced it with my eyes. It skirted the wooded foothills for some time before disappearing within them.

The sun bore down on me, hot and hard in the summer sky, as if it would drive me back to the palace. Yet I lingered. I had heard they were beautiful, our mountains—pears and cypress and streams of just-melted ice. It would be cool there and shaded. Far away from the diamond-bright beaches, and the flashing of the sea.

I could leave. The thought was sudden, arresting. I had come to the road meaning only to escape the sea. But the path lay before me, and the mountains. And Achilles. My chest rose and fell rapidly, as if trying to keep pace with my thoughts. I had nothing that belonged to me, not a tunic, not a sandal; they were Peleus’ all. I do not need to pack, even.

Only my mother’s lyre, kept in the wooden chest within the inner room, stayed me. I hesitated a moment, thinking I might try to go back, to take it with me. But it was already midday. I had only the afternoon to travel, before they would discover my absence— so I flattered myself—and send after me. I glanced back at the palace and saw no one. The guards were elsewhere. Now. It must be now.

I ran. Away from the palace, down the path towards the woods, feet stinging as they slapped the heat-baked ground. As I ran, I promised myself that if I ever saw him again, I would keep my thoughts behind my eyes. I had learned, now, what it would cost me if I did not. The ache in my legs, the knifing heaves of my chest felt clean and good. I ran.

Sweat slicked my skin, fell upon the earth beneath my feet. I grew dirty, then dirtier. Dust and broken bits of leaves clung to my legs. The world around me narrowed to the pounding of my feet and the next dusty yard of road.

Finally, after an hour? Two? I could go no farther. I bent over in pain, the bright afternoon sun wavering to black, the rush of blood deafening in my ears. The path was heavily wooded now, on both sides, and Peleus’ palace was a long way behind me. To my right loomed Othrys, with Pelion just beyond it. I stared at its peak and tried to guess how much farther. Ten thousand paces? Fifteen? I began to walk.

Hours passed. My muscles grew wobbly and weak, my feet jumbled together. The sun was well across the zenith now, hanging low in the western sky. I had four, perhaps five, hours until dark, and the peak was as far as ever. Suddenly, I understood: I would not reach Pelion by nightfall. I had no food, nor water, nor hope of shelter. I had nothing but the sandals on my feet and the soaked tunic on my back.

I would not catch up to Achilles, I was sure of that now. He had left the road and his horse long ago, was now moving up the slopes on foot. A good tracker would have observed the woods beside the road, could have seen where the bracken was bent or torn, where a boy had made a path. But I

was not a good tracker, and the scrub by the road looked all the same to me. My ears buzzed dully— with cicadas, with the shrill calls of birds, with the rasp of my own breath. There was an ache in my stomach, like hunger or despair.

And then there was something else. The barest sound, just at the limit of hearing. But I caught it, and my skin, even in the heat, went cold. I knew that sound. It was the sound of stealth, of a man attempting silence. It had been just the smallest misstep, the giving way of a single leaf, but it had been enough.

I strained to listen, fear jumping in my throat. Where had it come from? My eyes tracked the woods on either side. I dared not move; any sound would echo loudly up the slopes. I had not thought of dangers as I ran, but now my mind tumbled with them: soldiers, sent by Peleus or Thetis herself, white hands cold as sand on my throat. Or bandits. I knew that they waited by roads, and I remembered stories of boys taken and kept until they died of misuse. My fingers pinched themselves white as I tried to still all breath, all movement, to give nothing away. My gaze caught on a thick clutch of blooming yarrow that could hide me. Now. Go.

There was movement from the woods at my side, and I jerked my head towards it. Too late. Something—someone—struck me from behind, throwing me forward. I landed heavily, facedown on the ground, with the person already on top of me. I closed my eyes and waited for a knife.

There was nothing. Nothing but silence and the knees that pinned my back. A moment passed, and it came to me that the knees were not so very heavy and were placed so that their pressure did not hurt.

“Patroclus.” Pa-tro-clus . I did not move.

The knees lifted, and hands reached down to turn me, gently, over.

Achilles was looking down at me.

“I hoped that you would come,” he said. My stomach rolled, awash with nerves and relief at once. I drank him in, the bright hair, the soft curve of his lips upwards. My joy was so sharp I did not dare to breathe. I do not know what I might have said then. I’m sorry, perhaps. Or perhaps something more. I opened my mouth.

“Is the boy hurt?”

A deep voice spoke from behind us both. Achilles’ head turned. From where I was, beneath him, I could see only the legs of the man’s horse— chestnut, fetlocks dulled with dust.

The voice again, measured and deliberate. “I am assuming, Achilles Pelides, that this is why you have not yet joined me on the mountain?”

My mind groped towards understanding. Achilles had not gone to Chiron. He had waited, here. For me.

“Greetings, Master Chiron, and my apologies. Yes, it is why I have not come.” He was using his prince’s voice.

“I see.”

I wished that Achilles would get up. I felt foolish here, on the ground beneath him. And I was also afraid. The man’s voice showed no anger, but it showed no kindness, either. It was clear and grave and dispassionate.

“Stand up,” it said. Slowly, Achilles rose.

I would have screamed then, if my throat had not closed over with fear. Instead I made a noise like a half-strangled yelp and scrambled backwards.

The horse’s muscular legs ended in flesh, the equally muscular torso of a man. I stared—at that impossible suture of horse and human, where smooth skin became a gleaming brown coat.

Beside me Achilles bowed his head. “Master Centaur,” he said. “I am sorry for the delay. I had to wait for my companion.” He knelt, his clean tunic in the dusty earth. “Please accept my apologies. I have long wished to be your student.”

The man’s—centaur’s—face was serious as his voice. He was older, I saw, with a neatly trimmed black beard.

He regarded Achilles a moment. “You do not need to kneel to me, Pelides. Though I appreciate the courtesy. And who is this companion that has kept us both waiting?”

Achilles turned back to me and reached a hand down. Unsteadily, I took it and pulled myself up.

“This is Patroclus.”

There was a silence, and I knew it was my turn to speak. “My lord,” I said. And bowed.

“I am not a lord, Patroclus Menoitiades.”

My head jerked up at the sound of my father’s name.

“I am a centaur, and a teacher of men. My name is Chiron.”

I gulped and nodded. I did not dare to ask how he knew my name.

His eyes surveyed me. “You are overtired, I think. You need water and food, both. It is a long way to my home on Pelion, too long for you to walk. So we must make other arrangements.”

He turned then, and I tried not to gawk at the way his horse legs moved beneath him.

“You will ride on my back,” the centaur said. “I do not usually offer such things on first acquaintance. But exceptions must be made.” He paused. “You have been taught to ride, I suppose?”

We nodded, quickly.

“That is unfortunate. Forget what you learned. I do not like to be squeezed by legs or tugged at. The one in front will hold on to my waist, the one behind will hold on to him. If you feel that you are going to fall, speak up.”

Achilles and I exchanged a look, quickly. He stepped forward.

“How should I— ?”

“I will kneel.” His horse legs folded themselves into the dust. His back was broad and lightly sheened with sweat. “Take my arm for balance,” the centaur instructed. Achilles did, swinging his leg over and settling himself.

It was my turn. At least I would not be in front, so close to that place where skin gave way to chestnut coat. Chiron offered me his arm, and I took it. It was muscled and large, thickly covered with black hair that was nothing like the color of his horse half. I seated myself, my legs stretched across that wide back, almost to discomfort.

Chiron said, “I will stand now.” The motion was smooth, but still I grabbed for Achilles. Chiron was half as high again as a normal horse, and my feet dangled so far above the ground it made me dizzy. Achilles’ hands rested loosely on Chiron’s trunk. “You will fall, if you hold so lightly,” the centaur said.

My fingers grew damp with sweat from clutching Achilles’ chest. I dared not relax them, even for a moment. The centaur’s gait was less symmetrical than a horse’s, and the ground was uneven. I slipped alarmingly upon the sweat-slick horsehair.

There was no path I could see, but we were rising swiftly upwards through the trees, carried along by Chiron’s sure, unslowing steps. I winced every time a jounce caused my heels to kick into the centaur’s sides.

As we went, Chiron pointed things out to us, in that same steady voice.

There is Mount Othrys.

The cypress trees are thicker here, on the north side, you can see.

This stream feeds the Apidanos River that runs through Phthia’s lands.

Achilles twisted back to look at me, grinning.

We climbed higher still, and the centaur swished his great black tail, swatting flies for all of us.

C HIRON STOPPED SUDDENLY, and I jerked forward into Achilles’ back. We were in a small break in the woods, a grove of sorts, half encircled by a rocky outcrop. We were not quite at the peak, but we were close, and the sky was blue and glowing above us.

“We are here.” Chiron knelt, and we stepped off his back, a bit unsteadily.

In front of us was a cave. But to call it that is to demean it, for it was not made of dark stone, but pale rose quartz.

“Come,” the centaur said. We followed him through the entrance, high enough so that he did not need to stoop. We blinked, for it was shadowy inside, though lighter than it should have been, because of the crystal walls. At one end was a small spring that seemed to drain away inside the rock.

On the walls hung things I did not recognize: strange bronze implements. Above us on the cave’s ceiling, lines and specks of dye shaped the constellations and the movements of the heavens. On carved shelves were dozens of small ceramic jars covered with slanted markings. Instruments hung in one corner, lyres and flutes, and next to them tools and cooking pots.

There was a single human-sized bed, thick and padded with animal skins, made up for Achilles. I did not see where the centaur slept. Perhaps he did not.

“Sit now,” he said. It was pleasantly cool inside, perfect after the sun, and I sank gratefully onto one of the cushions Chiron indicated. He went to the spring and filled cups, which he brought to us. The water was sweet and

fresh. I drank as Chiron stood over me. “You will be sore and tired tomorrow,” he told me. “But it will be better if you eat.”

He ladled out stew, thick with chunks of vegetables and meat, from a pot simmering over a small fire at the back of the cave. There were fruits, too, round red berries that he kept in a hollowed outcropping of rock. I ate quickly, surprised at how hungry I was. My eyes kept returning to Achilles, and I tingled with the giddy buoyancy of relief. I have escaped.

With my new boldness, I pointed to some of the bronze tools on the wall. “What are those?”

Chiron sat across from us, his horse-legs folded beneath him. “They are for surgery,” he told me.

“Surgery?” It was not a word I knew.

“Healing. I forget the barbarities of the low countries.” His voice was neutral and calm, factual. “Sometimes a limb must go. Those are for cutting, those for suturing. Often by removing some, we may save the rest.” He watched me staring at them, taking in the sharp, saw-toothed edges. “Do you wish to learn medicine?”

I flushed. “I don’t know anything about it.”

“You answer a different question than the one I asked.”

“I’m sorry, Master Chiron.” I did not want to anger him. He will send me back.

“There is no need to be sorry. Simply answer.”

I stammered a little. “Yes. I would like to learn. It seems useful, does it not?”

“It is very useful,” Chiron agreed. He turned to Achilles, who had been following the conversation.

“And you, Pelides? Do you also think medicine is useful?”

“Of course,” Achilles said. “Please do not call me Pelides. Here I am—I am just Achilles.”

Something passed through Chiron’s dark eyes. A flicker that was almost amusement.

“Very well. Do you see anything you wish to know of?”

“Those.” Achilles was pointing to the musical instruments, the lyres and flutes and seven-stringed kithara. “Do you play?”

Chiron’s gaze was steady. “I do.”

“So do I,” said Achilles. “I have heard that you taught Heracles and Jason, thick-fingered though they were. Is it true?”

“It is.”

I felt a momentary unreality: he knew Heracles and Jason. Had known them as children.

“I would like you to teach me.”

Chiron’s stern face softened. “That is why you have been sent here. So that I may teach you what I know.”

I N THE LATE AFTERNOON LIGHT, Chiron guided us through the ridges near the cave. He showed us where the mountain lions had their dens, and where the river was, slow and sun-warm, for us to swim.

“You may bathe, if you like.” He was looking at me. I had forgotten how grimy I was, sweat-stained and dusty from the road. I ran a hand through my hair and felt the grit.

“I will too,” Achilles said. He pulled off his tunic and, a moment after, I followed. The water was cool in the depths, but not unpleasantly so. From the bank Chiron taught still: “Those are loaches, do you see? And perch. That is a vimba, you will not find it farther south. You may know it by the upturned mouth and silver belly.”

His words mingled with the sound of the river over its rocks, soothing any strangeness there might have been between Achilles and me. There was something in Chiron’s face, firm and calm and imbued with authority, that made us children again, with no world beyond this moment’s play and this night’s dinner. With him near us, it was hard to remember what might have happened on the day by the beach. Even our bodies felt smaller beside the centaur’s bulk. How had we thought we were grown?

We emerged from the water sweet and clean, shaking our hair in the last of the sun. I knelt by the bank and used stones to scrub the dirt and sweat from my tunic. I would have to be naked until it dried, but so far did Chiron’s influence stretch that I thought nothing of it.

We followed Chiron back to the cave, our wrung-dry tunics draped over our shoulders. He stopped occasionally, to point out the trails of hare and corncrakes and deer. He told us we would hunt for them, in days to come, and learn to track. We listened, questioning him eagerly. At Peleus’ palace there had been only the dour lyre-master for a teacher, or Peleus himself,

half-drowsing as he spoke. We knew nothing of forestry or the other skills Chiron had spoken of. My mind went back to the implements on the cave’s wall, the herbs and tools of healing. Surgery was the word he had used.

It was almost full dark when we reached the cave again. Chiron gave us easy tasks, gathering wood and kindling the fire in the clearing at the cave’s mouth. After it caught, we lingered by the flames, grateful for their steady warmth in the cooling air. Our bodies were pleasantly tired, heavy from our exertions, and our legs and feet tangled comfortably as we sat. We talked about where we’d go tomorrow, but lazily, our words fat and slow with contentment. Dinner was more stew, and a thin type of bread that Chiron cooked on bronze sheets over the fire. For dessert, berries with mountain- gathered honey.

As the fire dwindled, my eyes closed in half-dreaming. I was warm, and the ground beneath me was soft with moss and fallen leaves. I could not believe that only this morning I had woken in Peleus’ palace. This small clearing, the gleaming walls of the cave within, were more vivid than the pale white palace had ever been.

Chiron’s voice, when it came, startled me. “I will tell you that your mother has sent a message, Achilles.”

I felt the muscles of Achilles’ arm tense against me. I felt my own throat tighten.

“Oh? What did she say?” His words were careful, neutral.

“She said that should the exiled son of Menoitius follow you, I was to bar him from your presence.”

I sat up, all drowsiness gone.

Achilles’ voice swung carelessly in the dark. “Did she say why?” “She did not.”

I closed my eyes. At least I would not be humiliated before Chiron, the tale of the day at the beach told. But it was bare comfort.

Chiron continued, “I assume you knew of her feelings on the matter. I do not like to be deceived.”

My face flushed, and I was glad of the darkness. The centaur’s voice sounded harder than it had before.

I cleared my throat, rusty and suddenly dry. “I’m sorry,” I heard myself say. “It is not Achilles’ fault. I came on my own. He did not know that I would. I did not think—” I stopped myself. “I hoped she would not notice.”

“That was foolish of you.” Chiron’s face was deep in shadow. “Chiron—” Achilles began, bravely.

The centaur held up a hand. “As it happens, the message came this morning, before either of you arrived. So despite your foolishness, I was not deceived.”

“You knew?” This was Achilles. I would never have spoken so boldly. “Then you have decided? You will disregard her message?”

Chiron’s voice held a warning of displeasure. “She is a goddess, Achilles, and your mother besides. Do you think so little of her wishes?”

“I honor her, Chiron. But she is wrong in this.” His hands were balled so tightly I could see the tendons, even in the low light.

“And why is she wrong, Pelides?”

I watched him through the darkness, my stomach clenching. I did not know what he might say.

“She feels that—” He faltered a moment, and I almost did not breathe. “That he is a mortal and not a fit companion.”

“Do you think he is?” Chiron asked. His voice gave no hint of the answer.

“Yes.”

My cheeks warmed. Achilles, his jaw jutting, had thrown the word back with no hesitation.

“I see.” The centaur turned to me. “And you, Patroclus? You are worthy?”

I swallowed hard. “I’m not sure if I’m worthy. But I want to stay.” I paused and swallowed again. “Please.”

A heavy silence followed. Then Chiron spoke, his tone inscrutable. “When I brought you both here, I had not yet decided what to do. Thetis sees many faults—some real, some imagined.”

Hope and despair flickered within me like shifting flames.

“She is young and carries the biases of her kind. I am older and flatter myself that I can discern a man’s worth more clearly. I have no objections to Patroclus being your companion.”

A wave of relief washed over me, leaving me feeling as if a storm had passed.

“She may not be pleased, but I have faced the ire of gods before.” He paused. “And now it is late. Time for you to sleep.”

“Thank you, Master Chiron,” Achilles said, his voice full of earnest gratitude. We stood, but I hesitated.

“I just want—” I reached out slightly toward Chiron. Achilles understood and quietly disappeared into the cave.

I faced the centaur. “I will leave if there will be trouble.”

There was a long pause, and for a moment, I wondered if he had heard me. Finally, he said, “Do not let what you gained today be easily lost.”

With that, he wished me good night, and I turned to join Achilles in the cave.
