The ice on the River Ouse did not melt in the spring. It cracked.

Margaret woke with the sound of it. A sharp, crystalline shriek that tore through the heavy wool of her bedroll. She lay still, breathing in the cold air of the dormitory, her heart hammering against her ribs like a trapped bird. The dream was still clinging to her eyelids. In the dream, she had been standing on the bridge, the one that spanned the water, holding a basket of white lilies. But the lilies were rotting, black and slimy, and the ice beneath her feet was thinning, turning translucent. She had seen her own reflection in the water below, not as she was now—gaunt, hollow-eyed, dressed in the roughspun grey of the penitent— but as she had been. Young. Radiant. The daughter of the Duke.

She sat up. The straw tickled her neck. The other nuns in the cell slept, their forms indistinct in the gloom, but Margaret knew they were awake. They always were. The silence of the Abbey of St. Jude’s was not empty; it was full of watching eyes.

Margaret was a prisoner, though she wore no chains. The King had sent her here. Not for murder, for that would have meant a swift, merciful end. Not for treason, for that would have meant a public spectacle. He had sent her here because he could not forgive her, and because he could not kill her. She had refused the marriage. She had looked at the young Earl, a boy with soft hands and a harder heart, and she had said no. She had chosen the river. She had chosen the cold. And so, the King had taken her from the palace, from the silk and the warmth, and cast her into this stone box by the water, to rot until she remembered her place.

The Abbot found her in the chapel at dawn. He was a small man, with a face like a dried apple, and he smelled of wet dog and old incense.

"You walk the causeway again," he said. His voice was dry, like leaves skittering on pavement.

"The ice is breaking, Abbot," Margaret said. She did not look at him. She kept her eyes on the altar, where the candle burned low. "It is time to open the way."

"The river is not a way," the Abbot replied. "It is a wall. And you are on the wrong side."

"I am on the only side that matters," she said. "The side of the truth."

The Abbot sighed. It was a sound of profound exhaustion. "You speak of truth as if it were a coin you could spend. It is a weight. It crushes. Go to the garden. Pull the weeds. The King’s men are coming at noon. They expect you to be kneeling in the mud."

Margaret turned to leave, but the Abbot’s hand caught her sleeve. It was a light touch, but it held her fast.

"Margaret," he said. "Do you remember the night the bridge froze?"

She froze. Her breath caught in her throat. "I remember nothing but the cold."

"You remember the lilies," he whispered. "You threw them into the water. You wanted to see if they would float. They sank. They drowned. And the ice sealed over them. You have been waiting for them to rise for ten years."

Margaret pulled her arm free. "They are not mine to retrieve."

"No," the Abbot said. "But you built the bridge to keep them there."

She walked to the garden. The air was bitter, biting at her exposed skin. The garden was a patch of bare earth, surrounded by high walls that climbed toward the grey sky. There were no flowers here. Only the ghost of them, the dark stumps of roots waiting for a spring that might never come. Margaret knelt. She pulled a weed from the soil. Then another. Her hands were red, the knuckles split and bleeding. She did not feel the pain. The pain was a distant thing, a story told by someone else.

She had loved the river. That was the secret. Not the King, not the Earl, not the comfort of the palace. She had loved the cold, indifferent, beautiful violence of the river. She had loved the way it took everything and gave nothing back. She had built her life around that love, like a spider weaves a web. She had used her beauty, her wit, her family name, to build a bridge to the water. And when the King tried to cut that bridge, she had not resisted. She had simply let it fall.

But the bridge had not fallen. It had frozen. It had become part of her.

A sound reached her from the gate. The clatter of hooves. The shout of men. The King’s guard.

Margaret stood. She wiped the dirt from her hands on her grey skirt. She walked to the gate. The guards were there, two large men in steel that gleamed dully in the weak light. Behind them, a carriage. Black. Closed.

The lead guard stepped forward. He was a man named Thomas, or perhaps Tom. She had not seen his face clearly in years. He looked older. Harder. The softness that had once been in his eyes was gone, replaced by a flat, functional blankness.

"Margaret," he said. "The King requests your presence."

"I am not present," Margaret said. "I am here. There is a difference."

Thomas blinked. "The ice is gone. The bridge is open. The King is on the other side."

Margaret looked past him. The river was visible now, through the iron bars of the gate. The ice was indeed gone. The water was dark, churning, alive. It was beautiful. It was terrible. It was the thing she had been waiting for.

"And what does the King want with me?" she asked.

"To speak," Thomas said. "To settle the matter."

"To kill me?"

Thomas looked at her, and for a moment, something flickered in his face. Not sympathy. Not regret. Just a kind of tired recognition. "To save you," he said. "From yourself."

Margaret laughed. It was a short, sharp sound, like a branch snapping. "I am already saved. I am free. The bridge is broken."

"The bridge is not broken," Thomas said. "It is waiting."

He held out his hand. A key. Iron, cold, heavy.

"Put your hand in the water," he said.

Margaret stared at him. "What?"

"Put your hand in the water. Touch the current. And you will know if the bridge is gone."

She looked at the river. The water was rushing, gray and fast. It was the same water she had seen in her dream. The same water that had swallowed the lilies. The same water that had taken her youth, her name, her life.

She stepped out of the garden. The guards did not stop her. They stepped back, as if they had been waiting for this moment. As if they were afraid of what would happen.

Margaret walked to the riverbank. The mud was soft, sucking at her feet. She rolled up the sleeve of her grey dress. The fabric was rough, scratching her skin. She held her hand over the water.

The cold hit her before she touched it. A wave of it, invisible and powerful, striking her face, her eyes, her heart. She could feel the pull of it. The hunger of it. It wanted her. It had always wanted her. It was not a place. It was a person. It was the love she had made for herself.

She closed her eyes. She remembered the first time she had seen the river. She was five. Her father had carried her to the bank. She had reached out, and the water had caught her finger. She had not pulled away. She had watched the water swirl around her skin, cool and smooth. She had felt a connection. A bond. A chain.

She opened her eyes. She looked at her hand. It was trembling.

She dipped her fingers into the water.

The shock was electric. It traveled up her arm, into her shoulder, into her chest. She gasped. The cold was not just cold. It was memory. It was the lilies. It was the ice. It was the years of waiting. It was the silence of the chapel. It was the Abbot’s dry voice. It was Thomas’s tired face.

She pulled her hand out. The water dripped from her fingers, falling back into the current.

The bridge was not gone.

It was inside her.

She had built it with her love. She had reinforced it with her pride. She had braced it with her suffering. It was the only thing holding her together. Without it, she would be nothing. She would be a body, a name, a corpse. The bridge was her identity. Her self.

And the King was on the other side.

She turned back to Thomas. He was watching her. His eyes were wet.

"I understand," she said.

"Do you?" Thomas asked. "Do you understand that you cannot break it? That it is part of you? That if you let it go, you will drown?"

Margaret looked at the water. The current was pulling at her feet. She felt the tug. The irresistible, seductive pull of the void.

"I don't want to drown," she said. "I want to cross."

"You cannot cross," Thomas said. "You can only sink."

Margaret looked at her hand. The water had dried. There was no mark. No scar. Just skin.

She thought of the lilies. They had sunk. They had drowned. They had become part of the river. Was that not a kind of freedom? To be part of the water? To be part of the cold?

She looked at Thomas. "Is that what you want for me?" she asked. "To be part of the water?"

Thomas shook his head. "I want you to be free. Free of the bridge. Free of the cold. Free of the King."

"But I am the bridge," Margaret said. "I am the cold."

"No," Thomas said. "You are the woman who built it. And you can unbuild it."

Margaret looked at the river. The water was churning. It was alive. It was indifferent. It did not care about her. It did not love her. It did not hate her. It just was.

She realized, then, that she had been in love with the wrong thing. She had been in love with the power of the river. The power to destroy. The power to take. She had mistaken that power for love. But it was not love. It was death.

And she was tired of death.

She walked back to the gate. Thomas followed her. The carriage was still there. The black doors were open.

Margaret stepped into the carriage. It was warm inside. Smelled of leather and old perfume. She sat down. The cushions were soft.

Thomas closed the door.

"Where are we going?" Margaret asked.

"North," Thomas said. "Away from the river."

Margaret looked out the window. The river was disappearing, blurred by the glass. The ice was gone. The bridge was gone.

She closed her eyes. She felt the cold in her bones. It was still there. It would always be there. But it was no longer the only thing. It was just a memory. A scar.

The carriage rolled forward. The wheels clattered on the cobblestones. Margaret sat in the silence, feeling the vibration of the wheels in her chest. She was going away from the water. She was going away from the bridge.

She was going to live.

And that was the most terrifying thing she had ever done.
