Caelan Thorne had not slept, and he saw no reason to pretend otherwise.

At the third bell he gave up the cot in the corner of the map room and sat at the long table with the night's storm reports spread before him: wind speeds from the outer wards, barometer readings from the storm-glass room, a tally of ward damage in Bram's cramped hand. Two wards cracked at the crown, one scorched black. No casualties. A small mercy. He read each page twice and retained almost none of it.

The bond hummed.

It was not a sound. He had tried for an hour to find a better word and had failed. It was a pressure behind the breastbone, a faint steady vibration like a bell struck once, a long way off, whose note has not quite died. It was neither pain nor comfort. It simply was, and it was somewhere above him and to the west, three floors up in a narrow room with a lamp left burning.

He turned the page.

Last night, for the length of a held breath, he had felt her. That was the thing he kept circling and refusing to look at straight. The cord had flared and the door in his chest had come off its hinges, and a wild, bright, terrified feeling had poured through it: a flash of fury so pure it had made his teeth ache, and under the fury a small, desperate resolve. Not this time. Not again. And with it, absurdly, the smell of bread and wet wool.

Then she had torn her wrist out of his grip, and the door had slammed.

He had spent the rest of the night on the Line, walking the wards in the rain, because it was the only work that required nothing of him but attention. He had returned at dawn to find the infirmary door shut and Wren Ashby waiting in the passage with her hands folded and her eyes on the floor.

"She says she will cut it," Wren had told him. "She asked me to tell you so."

"Did she say how?"

"She does not know how." The old woman had still not looked up. "Nor do I."

He had known Wren Ashby since he was fourteen years old. He knew the sound of her voice when she was telling the truth, and he knew the other sound, and he had stood in that passage and listened to the other sound and said nothing, because he had no right to ask for more.

The lamp guttered. Outside, the morning bell began.

He squared the reports into a stack and set the badge on top to hold them down.

* * *

She came to him at the seventh bell, as he had known she would.

He heard her on the stair before he saw her. A quick, even tread, nothing wasted. She stopped in the doorway of the map room in a clean grey blouse and a plain skirt, with her hair pinned back so severely that it pulled at the corners of her eyes. The silver line around her left wrist was almost invisible in the daylight. She kept that arm very slightly behind her.

She was pale. There were violet smudges under her eyes. She was standing perfectly straight.

"Warden," she said.

"Stormbinder. Have you eaten?"

The question left his mouth before he had weighed it, and he watched it land. Her chin rose a fraction.

"I am told Tamsin Hale will be checking."

"Then she will." He set down his pen. "You are well enough to be on your feet?"

"I am well enough to make a request."

"Make it."

"I would like to be quartered at the Sable Point station."

He had known that, too. Sable Point lay at the southern edge of the Line, a stone hut and a signal mast four miles down the coast. It was as far as any post could be and still be called Calder Port.

"No," said Caelan.

The silence that followed was very polite.

"May I ask the reason?"

"The bond."

"The bond is silent."

"It is not silent. It is quiet. That is a different thing." He kept his voice even. "Last night it held a storm in place for a quarter of an hour. I do not know what it does at four miles, and neither do you. I will not find out by sending a Binder south on her own and waiting to see what happens."

"I am not asking you to wait to see what happens. I am asking to be reassigned."

"You have been reassigned. To here."

"By you."

"Yes."

She held his eyes for a long moment. Her voice, when it came, was so level and so civil that it might have been carved from glass. "I see. Then it is my understanding, Warden, that the Line does not value my judgment of my own safety."

"The Line values your safety. Your judgment of it is under review."

Something flickered across her face. It was gone before he could name it. He would have called it, in another woman, the beginning of a laugh, instantly strangled.

"That is fine," said Sera.

It was not fine. He had read three years of her written reports and she had never once used the word fine about anything that was.

"If that is all," she said, "I'll see to the wards on the north headland."

"Stay within the tower grounds today."

"I heard you the first time."

She turned and went out, and he listened to her steps recede down the stair, quick and even, nothing wasted.

He picked up his pen. The note in his chest rang on, far and faint.

He did not have to wait long.

* * *

The meeting with Bram was in progress, a dull one, concerning the replacement of the two cracked wards. Bram had a way of laying out a problem as if setting a table: each piece placed squarely, nothing hurried. Caelan was halfway through approving a requisition of iron stock when the first lurch came.

It began in his chest. The bell that had hummed softly all morning suddenly clanged, flat and wrong. His heart stumbled over two beats and then raced. The map table seemed to tilt a quarter inch toward the window.

"Caelan?" said Bram.

"One moment."

He set both hands flat on the table. The room smeared at the edges. A cold sweat broke along his spine. It was not like a wound, nothing he could locate and press, only a sick, spreading wrongness, as though something had been pulled taut inside him and was beginning to fray.

He knew, in the way that one knows a fact before it has been explained, exactly what she had done.

"Where is she?" he said.

Bram's eyes sharpened. "The Stormbinder? She went out about twenty minutes ago. She said she was to inspect the harbor wards."

"Which direction?"

"Along the wall, I think. Caelan, you've gone grey..."

He was already moving.

The stairs went by in a jolting blur. He took them two at a time with one hand on the rail, and the nausea rose with every landing, a high thin whine behind his ears. He burst out of the tower door into a bright, hard, windy morning, and the harbor wall stretched out ahead of him, long and pale and lined with iron lamp posts.

She was sitting on the stones at the foot of the third lamp post from the end.

Sitting, not lying. She had her back against the iron and her knees drawn up and her head tipped back against the post, eyes closed. Even from forty paces he could see her chest rising too fast. A strand of hair had come loose from its pins and was whipping across her mouth.

He covered the distance without feeling it. The whine in his ears climbed and then, a single step from her, cut off all at once, as if a hand had been lifted from his skull. His own breathing steadied. The wall stopped swaying.

He had come back within range.

"Valdis."

Her eyes opened. They were grey, he saw, a clear, cold, rain-water grey that had nothing of silver in it in daylight, and they went from his face to his boots and back with something very like loathing.

"One hundred and eleven," she said, thinly. "I counted. That's where it started."

He crouched in front of her. "You counted."

"I wanted to know."

"You could have asked Wren."

"Wren doesn't know." Her mouth twisted. "I've noticed that Wren doesn't know a good many things."

He let that pass. He held out a hand to help her up, palm open, nothing more, and watched her look at it as though he had offered her a live eel.

"I can stand."

"I did not say you couldn't."

She put one hand against the lamp post and pushed herself up in stages, jaw locked, and he stayed where he was, close enough to catch her and not touching her. She swayed once. She did not fall. When she was upright her eyes were a little too bright and her lips were bloodless, and he understood that she had been dizzy for several minutes and had refused to move because moving was the same as admitting it.

"Are you going to say it?" said Sera.

"Say what?"

"That I was wrong."

"You weren't wrong." He turned his head toward the tower. "You were testing a theory. It was a sound one. It is also a method I would ask you not to repeat alone."

She looked at him as if she were waiting for the trap in that sentence to spring. It did not. After a moment she turned and began walking back along the wall, a little too fast, one hand trailing along the lamp posts as she passed them.

He fell in behind her at four paces. At every lamp post the humming in his chest eased.

* * *

By noon the whole of the tower's upper floor had assembled in the map room, and Caelan stood at the head of the table with his arms folded and his jaw tight, aware that he was about to hold a meeting about the one thing in his life that he could not command.

Bram sat with his chair tipped back, eyes sharp. Tamsin had a notebook open on her knee and a pencil behind her ear. Wren Ashby had taken the chair nearest the fire, hands wrapped around a bowl of broth she was not drinking. And at the far end, as far as the table allowed, sat Sera Valdis with her back straight and her eyes fixed on the middle distance.

"The facts," said Caelan. "We have an active bond between a Warden and a Binder. It was not intended and it is not understood. Binder Valdis has established, at some cost to herself, that it exerts a physical effect at distance. I want that effect measured."

"We have a figure of a hundred and eleven paces from her count," said Tamsin, writing. "Give or take. From his side it'd be less, he was already moving when he felt it, so we won't know until..."

"A hundred," said Caelan. "We will say a hundred."

"It isn't exact."

"It is conservative." He looked at Wren. "Is there anything in the records?"

Wren kept her eyes on her bowl. "There is nothing I have read that describes it."

It was the phrase he had heard in the passage that morning, the careful shape of it. *Nothing I have read.* Not *nothing there is.* He looked at her for one second longer than courtesy required. She did not look up.

"Then we proceed from the working assumption," he said, "that the bond has a range of approximately one hundred paces, and that exceeding it causes sickness in both parties, increasing with distance. Until we know more, we operate inside that range. Both of us. At all times."

"At all times?" said Sera.

"When on duty, certainly. Off duty, the assumption holds."

"You mean to say that I must sleep within a hundred paces of you."

"I mean that you must be within a hundred paces of me. How you arrange it is up to you."

Bram made a very small noise. Tamsin looked at her notebook with great intensity.

"The tower has forty rooms," Caelan went on, doggedly. "Yours is on the third floor, mine is on the second. It is well inside the figure. It is not a punishment. It is a precaution."

"Understood," said Sera.

Her voice was perfectly flat. She was not looking at him. She was looking at the corner of the table, and he could see a muscle moving in her jaw.

"I have terms," she said.

"Name them."

"I will comply with the range. I will attend to my duties and I will cooperate in any investigation into the bond. In return, we will not discuss anything that is not Line business." She looked up. "Nothing personal. Not one word. I want that understood."

The room was very quiet. Even the fire seemed to hold its breath.

He thought of the step of a doorway, three days after, and the rain on a hat brim, and a girl's face in the gap with the door half closed. He thought of a thin, off-key tune, hummed over dishes. He thought about all the things he could have said and the one promise that stood between them and the saying.

"I won't argue that," said Caelan.

It was meant as a concession. He saw at once that it had been taken as the opposite.

Her eyes flared, bright and hard, and something close to disgust crossed her face. It was the look of a woman who had braced for a blow and been handed, instead, a courteous bow. For a moment she looked as if she meant to strike him anyway.

"Good," said Sera, very quietly, and the single word was a door closing.

She rose, inclined her head to the room, and walked out. Her steps on the stair were quick and even. She did not slam the door. Somehow it would have been better if she had.

"Well," said Tamsin, into the silence. "That went splendidly."

* * *

Bram caught him alone in the passage afterward, in the dim stretch beyond the storm-glass room where the brass instruments ticked in the dark.

They had served together for nine years. Bram was the only man on the coast who had seen him weep, and the only man who had never mentioned it since. He leaned against the wall with his arms crossed and his big face unusually grave.

"You owe her," Bram said.

"I know what I owe."

"Do you? Because I've been listening to you say 'you're right' to that woman for a quarter of an hour, and I don't think it's the same thing." He kept his voice low. "She's not asking for a report, Caelan. She's asking for a reason. Three years she's been carrying that around. You stood on her step, and you said nothing, and you've let her put the worst construction on it ever since."

"It is the construction I have earned."

"It's the one you've handed her." Bram's jaw worked. "There's something you aren't saying. I've known it since that night. I'm not asking what. I'm only telling you that if you've got a reason, now is the time to give it to her, because this thing..." He tipped his chin toward the stair. "This thing's going to put the two of you in a room together every day until one of you dies or learns to talk."

Caelan looked at the floor. The ticking of the instruments marked off seconds, steady and indifferent.

"I cannot," he said.

"Cannot, or will not?"

"Bram."

A long pause. Then the big man exhaled and pushed himself off the wall. "All right." He clapped Caelan once on the shoulder, heavily, as one steadies a horse. "But I'm saying it again in a week. And I'll keep saying it until you tell me to stop."

"You will have to say it to someone else. I am leaving the Line when this is over."

"No, you're not," said Bram, and went off down the passage, whistling a tuneless thing through his teeth.

* * *

Night came down hard and clear, stars sharp as pins above the headland, the sea an unbroken black. The Line burned along the cliff, thirty blue lights in a row, and nothing moved on the water.

Caelan climbed the stair to the third floor at the tenth bell, and stopped at the end of the passage.

He had no business there. The range of the bond ran a hundred paces and his own room was well inside it. There was no reason to go further than the landing. He stood in the dark with his shoulder against the cold stone and his hand resting, for no reason, on the badge at his chest.

Her door was at the far end, a thin line of lamplight beneath it. He could not hear her. The walls of the old tower were two feet thick. But the bond could, in some way he did not understand. Through the faint, steady ring of the far-off bell, he caught a change in the note. A softening. A tiny, ragged break, like a held breath released. A body shifting under blankets. Turning over.

He stood very still.

He did not know what she felt. He was not meant to. The bond gave him nothing of that, only the shape of her presence, as one feels the warmth of a fire through a closed door. But he knew she was awake. He knew she lay in the dark with the silver line on her wrist glowing against the sheets, and that she was thinking of a song.

He had heard Elowen sing it, once. Standing on the Harrow Coast road in the grey hour before the storm, hands braced on the wall of the seawall, her small voice soft and a little off-key under the wind. *Mama's tune,* she had said, when she saw him listening. *It keeps my hands steady.*

He took the badge from his coat. It was a plain, battered thing, bronze worn smooth at the edges, the Warden's wheel stamped into its face, and it had been his father's before him. He turned it over in his palm. His thumb found the worn place at the rim and moved along it, back and forth, in the old habit he had never been able to break.

In the dark, behind the wall, a woman he had wronged breathed in and out.

He did not knock. He did not call out. He stood in the passage until the lamplight beneath her door went out, and the faint ring in his chest settled into something almost like rest, and only then did he go down the stairs to the empty cot in the map room, where he lay on his back and stared at the ceiling and did not sleep.
