Chapter 1

Issa did not look up from the mosaic she was tracing with her sandal. "I did not."

"You absolutely did. Right on the toes. I felt it."

She lifted her chin, and the afternoon sun caught the gold in her dark hair. "Perhaps your feet are too large, Leandros. Have you considered that?"

He grinned, a flash of white against sun-browned skin, and shifted his weight off the foot she had indeed crushed. They were twelve years old, standing in the shade of the colonnade that bordered the Forum of Pompeii, while their fathers argued about grain shipments somewhere inside the Curia. The heat pressed down like a hand on the back of the neck, but the sea breeze from the harbor cut through it, carrying salt and the distant shouts of dockworkers.

Leandros leaned against a marble pillar, arms crossed. "Your mother told my mother you were learning to be diplomatic."

"I am being diplomatic. I'm not saying your feet are absurd. I'm merely suggesting they might be the reason you trip over your own toga."

He laughed, and she let herself smile. This was how they had always been—a rhythm of jabs and recoveries, learned over years of being thrown together while their parents conducted the business of empire. The House of Leandros, Roman through and through but with an Alexandrian grandmother who had brought papyrus scrolls and strange gods into the villa. The House of Isis, Greek-Egyptian by blood, Roman by citizenship, and wealthy enough to make the old families pretend not to notice.

Issa's mother had named her for the goddess, and the name clung to her like perfume. She was tall for her age, with her father's sharp nose and her mother's way of watching everything without appearing to move her eyes. Leandros was shorter, broader, with the restless energy of a boy who had never been told to sit still.

"They're taking forever," he said, nodding toward the Curia doors. "My father said we'd go to the harbor after. He promised."

"Your father promises a lot of things."

Leandros looked at her sharply, but she was not being cruel. It was simply true. Senator Marcus Leandros was a man of grand gestures and quick decisions, the kind of Roman who built ships and roads and alliances the way other men built walls. He had promised his son a trip to the harbor three times this month, and three times the Senate had intervened.

"He'll keep this one," Leandros said, but there was a question in it.

Issa shrugged. "Then we'll go to the harbor. And you'll fall in."

"I won't fall in."

"You always fall in."

This was also true. The last time they had gone to the harbor together, Leandros had leaned too far over the edge of a dock to look at a fishing boat and tumbled into the green water, emerging with seaweed draped over his head and a fish flopping in his tunic. Issa had laughed so hard she had to sit down. The fishermen had laughed too. Leandros had laughed last, once he was sure he was not drowning, and then he had chased her up the pier with the fish.

She missed that. She missed the easy days before their parents started looking at them differently, before the whispers about alliances and bonds began to circulate in the triclinia of the great houses.

The Curia doors opened, and the senators spilled out into the forum like water finding its level. Issa spotted her father first—tall, lean, his Greek accent still audible even in his silences—and then Leandros's father, broader and louder, clapping a hand on someone's shoulder and laughing at something that was probably not funny.

They walked toward their children with the satisfied air of men who had gotten what they wanted.

"The harbor," Marcus Leandros announced, his voice carrying across the marble. "I promised the boy the harbor, and the harbor he shall have. Issa, you'll join us. Your father agrees."

Issa's father inclined his head. He did not smile, but he did not frown either, which from him was a kind of warmth.

Leandros grabbed Issa's wrist and pulled her forward. "Come on, then. Before the tide changes."

"The tide doesn't change for another three hours," she said, but she was already running with him, their sandals slapping against the sun-warmed stone.

They wove through the crowd—merchants closing their stalls, slaves carrying baskets of bread and olives, a priest in white robes heading toward the Temple of Apollo. A dog barked at them from a doorway. Leandros veered around a woman with a crate of squawking chickens, and Issa followed, her braid swinging.

They emerged at the top of the steps that led down to the harbor, and the world opened. The Bay of Naples spread out before them, blue and silver and impossibly wide. Ships bobbed at anchor, their sails furled, their hulls painted with eyes to ward off evil. The air smelled of fish and tar and the sweet rot of rope.

Leandros stopped at the edge of the stone steps, breathing hard. "There. See? I haven't fallen yet."

"The day is young."

He turned and looked at her, and something in his face shifted. He was not a boy who thought much about the future—he lived in the present, in the heat and the noise and the salt spray—but in that moment, he seemed to be trying to see ahead. To see what they would become.

"Issa," he said, and then stopped.

"What?"

"Nothing. Just... stay close today. All right?"

She wanted to make a joke, to deflect with a barb about his feet or his tendency to fall into bodies of water. But she did not. She nodded instead, and they walked down to the harbor together, their shoulders brushing.

The day unfolded like a scroll. They watched a merchant ship unload amphorae of wine from Crete, listened to a sailor tell a story about a sea monster that turned out to be a whale, and ate flatbread with olive oil at a stall near the fish market. Leandros did not fall into the water, though he came close when a crate of fish guts slipped from a dockworker's hands and splattered at his feet. Issa grabbed his arm and pulled him back, and he looked at her with an expression she could not name.

By late afternoon, the heat had begun to ease, and they made their way back through the streets of Pompeii toward the Villa of Leandros on the slope of the hill. The house was old, older than the city itself in some ways, with walls that had soaked up generations of laughter and argument. The garden was cool and green, shaded by plane trees and watered by a fountain that burbled softly.

Issa's mother was already there, seated on a stone bench with a cup of wine, talking to Leandros's mother in the easy shorthand of women who had known each other for twenty years. They fell silent when the children entered, and then smiled, and Issa felt the weight of that silence settle on her shoulders.

Something was happening. Something they were not being told.

That evening, the villa filled with guests. Senators and their wives, merchants of the first rank, a priest from the Temple of Isis who kissed Issa's forehead and called her by the goddess's name. Torches were lit along the colonnade, and the triclinium was laid with couches and cushions and low tables heavy with food: roasted peacock, dormice in honey, oysters from the bay, figs and grapes and cheese.

Issa was placed on a couch near the head of the table, next to her mother. Leandros was across from her, on the other side, between his father and an empty space that seemed to have been left deliberately.

The feast went on for hours. There were toasts and speeches, poetry recited by a slave with a golden voice, a musician playing a lyre in the corner. Issa ate little and watched much. She watched the way the adults looked at her and Leandros, the way their eyes slid between them and then away. She watched Leandros's hands, restless on the table, picking at a piece of bread he was not eating.

He felt it too. She could tell.

When the last course had been cleared and the wine cups were refilled, Marcus Leandros stood. He was a large man, and the room seemed to shrink around him. He raised his cup, and the conversations fell away.

"Friends. Family. Honored guests." His voice filled the room, warm and commanding. "We have gathered tonight not only to feast, but to share news that has been long in the making. News that binds our houses together, as they have always been bound, but now in a way that will shape the future of this city, this province, and the empire itself."

Issa's stomach tightened. She looked at her father, but his face was unreadable.

Marcus Leandros turned, and his gaze fell on Leandros, then on Issa. He smiled, and it was the smile of a man who had planned this moment for years.

"My son, Leandros," he said, "and Issa, daughter of the House of Isis. It is my honor, and the honor of her father, to announce that these two will be bonded. Not as a mere arrangement of convenience, but as a covenant between Rome, Greece, and Egypt. A new alliance. A new beginning."

There was a moment of silence, and then the room erupted. Cheers, applause, the clinking of cups. Someone shouted a blessing. Someone else began to sing.

Issa did not hear any of it.

She looked across the table, over the flowers and the wine and the flickering lamplight, and found Leandros's eyes. He was not celebrating. He was not smiling. He was looking at her the way he had looked at her on the harbor steps, as if trying to see the future.

She had known this was coming. She had heard the whispers, seen the looks, felt the weight of expectation pressing down on her for months. But knowing and hearing were not the same as standing in the middle of a room full of people who were already planning her life.

Leandros raised his cup. Not a toast—a question. His eyes asked: Are you all right?

Issa lifted her own cup, just slightly, and answered: Yes.

It was not the whole truth. But it was enough for now.

Her father leaned over and touched her arm. "You will be happy," he said, and it was not a question.

Issa nodded, because that was what was expected, and she turned back to look at Leandros across the table. He was still watching her. The noise of the feast swirled around them, the songs and the laughter and the clatter of cups, but for a moment they were the only two people in the room.

And she realized, with a start that felt like falling, that she did not want this to be just politics.

She wanted it to be real.

Leandros set down his cup and smiled—a small smile, almost private, meant only for her—and Issa felt her own mouth curve in answer.

The night was warm, the stars were coming out over the Bay of Naples, and everything had changed.
