Prologue

The child would not stop watching the light, and the light was the one thing Sera could not let her keep.

They had been three days on the open Pale, and in all that time there had been no morning, because there were no mornings anymore, only the dark above and the dull red coal of the Ember sunk forever into the western edge of the world, and the salt going on white and white and white until the eye gave up. Sera walked with the baby bound to her chest under two coats, and she walked toward the one smudge of warm gold on the whole black horizon, which was the town of Lowmere, which was the last place in the world that anyone who loved her would think to look.

That was the point. That no one who loved her would think to look there.

The baby’s eyes were open. They were always open lately, dark and unblinking and turned up toward the little lamp that swung from Sera’s staff — a thumb of cheap graveglass, honey-colored, burning down to nothing. In its light the baby’s face was the only warm thing for a hundred miles. Sera looked at it and felt the old, animal want rise up in her: to stop, to sit down in the salt, to hold the warmth and let the cold come and have it over with. The Dark did that to you. It got into the place behind your eyes where you kept yourself and it whispered that there was no self worth keeping, that it would be a mercy to set the burden down.

She had spent her whole life learning not to listen to that voice. She knew, better than anyone left alive, exactly what it was.

“Not yet,” she told the baby, or told the cold, or told herself. “Not yet, not yet.”

Her breath went out in a rag of white. Behind her, far back across the salt, there was a second light.

She had been pretending for half a day that she hadn’t seen it. A single steady point, low and gold, neither gaining nor falling back, the way a lamp does not move when the one carrying it is patient. Sera knew patient men. She had loved one, once, which was its own kind of foolishness, and she had been hunted by his masters long enough to know that the patient ones were the ones who caught you. They did not run. They did not need to. They simply did not stop, and the world was a cold place to run through, and eventually you sat down.

She would not sit down.

She shifted the baby higher and felt, against her sternum, the harder thing she carried — the shard, wrapped in salt-cloth and bound with a cord, a piece of dull glass no longer than her thumb that gave off no light at all and never had. To any Reader who took it up it would seem a worthless thing, a stillborn life, a death so empty it had crystallized into nothing. That was the point of it too. That was the whole, terrible cleverness of it. Sera had carried it out of the deepest archive under the Hearth, past men who would have burned the city to keep it, and the reason she had been able to carry it at all was that it looked like nothing, weighed like nothing, shone like nothing — and was, in truth, the most dangerous object in the world.

It was a key. It was a name. It was the first word of a sentence that the Hearth had spent a thousand years making sure no one would ever finish.

And it would do nothing — nothing — in any hand but the right one.

She looked down again at the baby watching the lamp.

“You’ll hate me,” Sera said softly. The salt creaked under her boots. “If you live long enough to remember anything at all, you’ll hate me, and that’s — that’s the best of all the things I want for you, do you understand? I want you to live long enough to hate me.” She laughed, and it cracked in her throat. “What a thing. What a mother.”

Lowmere came up out of the dark slowly, the way all towns did: first the haze of gold against the black, then the shapes of it, the squat sloped roofs huddled around the throat of the Well, the one weak Beacon at the center that the people here called the Little Light. It was failing. Sera could see that from a mile out — could feel it, the way she felt all glasslight, as a warmth behind the eyes and a murmur under the skin, the bleed of ten thousand strangers’ lives bleeding gently into the cold. The Little Light’s murmur was thin and guttering. There were holes in it. Whole years of the dead had gone dark inside it already.

It was happening here too, then. It was happening everywhere. Sooner at the edges, where the light was thin to begin with, but everywhere.

You were right, she told the man she had loved, the one she would never see again, in the place in her head where she kept him. You were right and I was right and it doesn’t matter which of us was right, because they’re going to let it happen anyway. They’d rather hold the last of the light than understand it.

The second lamp behind her had stopped.

Sera turned. Out on the white, perhaps a mile back, the gold point hung still — and then, slowly, deliberately, it dipped twice. Up, down. Up, down. A Reader’s sign, old as the guild. I see you. I am not your enemy. Wait.

She stood a long moment with the wind pulling at her coats and the baby warm against her heart, and she let herself, just for the length of three breaths, believe it. That he had come not for the Hearth but for her. That he would take them both somewhere warm, that there was somewhere warm, that the thing she carried could be put into the right hands by someone other than herself and she could simply be a woman with a child and a man who loved her, in a lit room, with the door shut against the Dark.

Three breaths. That was all she allowed herself. She had always been able to count the cost of a thing exactly.

Because if he had come for her, then the men he answered to knew where she was. And if the men he answered to knew where she was, then the only way to keep the child safe was to make sure the child was no longer with her when they arrived.

“Right,” Sera whispered. “Right, then.”

She went the last half mile fast, before she could change her mind, into the gold haze of a dying town. There was a dead-house at the edge of it — there always was, at the edge, where the smell wouldn’t carry — and a low window with a candle in it, and inside, a woman with flour on her hands and a hard, tired, decent face, the kind of face that had buried too many of its own to turn away one more small body in the cold. Sera knew that face. She had been finding that face her whole flight, in town after town. It was the only kind of face she trusted now.

She did not give her real name. She gave the woman three things instead: the baby, and a story thin enough to be believed and dull enough to be forgotten, and a fold of coin that was more than the woman saw in a season and not so much as to be remembered. And then, when the woman’s hard hands had closed around the child — and the child had not cried, the child never cried, the child only watched — Sera took the shard from against her heart.

She almost kept it. For one moment, with her own death walking toward her across the salt, she almost kept the dangerous, useless, world-ending thing for herself, so that at least when they took her they would have to take it from her hands.

But that was vanity, and Sera had no use left for vanity.

She tucked the shard into the swaddling, against the baby’s back, where a busy poor woman would not think to look and a child too young to speak could not lose it. Wrapped in salt-cloth, bound with a cord. Dead and dull and shining with nothing.

It would wake when it was meant to wake. In the only hand it was meant to wake in. She had to believe that, because she was about to die for it.

“Her name is Wren,” Sera said — gave the woman that much, the one true thing, because a name is a candle and the child should have at least one lit for her in this world. “When she’s grown, if she ever — ” She stopped. Started again. “Tell her her mother loved the light. Tell her her mother thought it was worth more than it costs. Will you tell her that?”

“I’ll tell her,” the woman said, who did not understand any of it and would, Sera prayed, never have to.

Sera looked at her daughter one last time, watching the candle, dark eyes full of small gold flame, and she pressed the truth down into the deepest part of herself where not even the Dark could whisper it loose, and she turned and walked back out of the warmth.

Out past the last houses. Out past the Little Light’s failing edge, into the cold and the murmurless black, where the second lamp was closer now, close enough that she could almost make out the shape of the man behind it, the patient man, the man she had loved, coming the way he always came, slowly, without stopping, certain that the world would deliver to him anyone who simply ran long enough.

She would lead him east. Away from the gold haze. Away from the dead-house and the decent woman and the child watching the light. She would run until she could not run, and then she would do the only thing she had left that would keep them all guessing for a generation — she would make sure that whatever they took from her, they could never, ever read.

“Come on, then,” Sera said to the Dark, and smiled, and went to meet it.

Behind her, in a town too poor and too far and too forgotten for anyone to think to look, a child slept at last, and dreamed, if she dreamed, of nothing anyone could name — and against her small back, wrapped in salt-cloth, a piece of dead glass lay waiting, patient as a held breath, patient as the man on the salt, patient as the dark above a world that had forgotten it ever had a sun.

It would be sixteen years before it woke.
