The road to Thornwatch ran two days on foot through forest that got thinner and meaner the further north it went, until the tall pines of Blackthorn territory gave way to scrub and gray rock and a wind that never seemed to stop moving. Wren walked most of it alone, because the pack couldn't spare an escort for a healer's assistant nobody important, and told herself the silence was a gift, not a warning. Her chest still ached in that strange, directional way, like a held breath that never fully let go, and every few miles she caught herself pressing a hand flat against her sternum without meaning to, as if she could hold the cold place there still by force.
She saw the black furred wolf twice more.
The first time was at dusk on the first day, a shape at the top of a ridge that vanished the moment she looked directly at it, and her heart slammed so hard against her ribs that for a full minute she couldn't make her legs move at all. The second time was closer, close enough, on the second morning, that she caught the shape of it clearly for a full second before it melted back into the treeline, and the shape was wrong in a way she couldn't name until she'd walked another mile and it came to her: it was too big. Blackthorn wolves ran large, but this one carried itself like something built for a different kind of fighting, shoulders too broad, gait too controlled, the walk of a wolf who had never in its life had to worry about losing.
She didn't tell anyone, because there wasn't anyone to tell, and because some small stubborn part of her still hoped she was wrong, even while her own pulse refused to believe it, staying quick and thin in her throat the rest of the way north.
Thornwatch outpost, when she finally reached it on the evening of the second day, was smaller than she'd pictured and grimmer than Prewitt's warning had prepared her for, a huddle of stone buildings behind a wall half fallen in two places, a clinic with a roof that leaked in one corner and a supply cabinet that had clearly not been restocked properly in months. The dozen or so wolves stationed there looked at her with the particular flat exhaustion of people who had stopped expecting help to arrive and weren't sure what to do now that some had.
"You're the new healer," said a woman near the gate, older, missing two fingers on her left hand, sizing Wren up like she was inventory. "Prewitt's girl."
"Wren. Yes."
"Good." The woman didn't smile, exactly, but something in her shoulders eased half an inch. "Ironridge scouts have been getting bold. Lost a man to a border skirmish two weeks back, another with a leg wound that's healing wrong because nobody here knew how to set it properly. You any good?"
"I'm good," Wren said, and meant it, because it was the one thing about herself she'd never had to doubt.
The next four days blurred into work in a way that helped more than she expected. Setting the badly healed leg. Restocking what she could. Learning names: Garrick, the one eared captain who ran the post like a man determined not to lose anyone else; Tam, barely sixteen and desperate to prove he belonged on patrol; a handful of others sent here for reasons ranging from ordinary rotation to quiet punishment. But the work wasn't quiet, not really. Twice that first week the watch horn sounded over nothing more than a deer spooking the tripwires, and both times Wren's heart slammed into her throat before her mind caught up, because out here nothing and Ironridge scouts testing the wall sounded exactly the same from inside the clinic. Nobody at Thornwatch had heard the story from the calling field yet, and Wren found she could almost, for whole stretches of an hour, forget the ache sitting under her ribs where a bond had been born and murdered in the same breath. She never quite forgot the two black furred glimpses on the road. She caught herself checking the tree line every time she crossed the yard, waiting for eyes that didn't come back.
On the third evening, Garrick found her re-wrapping the badly healed leg by lamplight, frowning at the way the bone had knit crooked under a splint someone with more courage than training had set months ago.
"You'll have to break it again to fix it," he said, watching her hands work. Not a question either, the way most things out of his mouth weren't.
"Tomorrow, if he'll let me. It'll hurt worse before it heals right, and I want him ready for that, not surprised by it."
"That's more warning than most healers bother giving." Garrick lowered himself onto the bench across from her, joints cracking audibly, and studied her with the same unhurried assessment he'd given her the day she arrived. "Prewitt trained you well. Better than well, for someone who's spent three years playing assistant instead of healer."
"I wasn't allowed to be the healer while she was still standing."
"No." He turned his ruined ear toward the window, listening to something Wren couldn't hear, an old habit he did whenever the wind shifted. "For what it's worth, I don't care what happened on that field back home. Out here we don't have the luxury of caring who the moon did or didn't pick for who. We have the luxury of a healer who knows what she's doing, and I intend to keep her as long as I can."
It wasn't kindness, exactly, Garrick didn't seem built for it in any soft sense, but it landed like kindness anyway, the practical sort that didn't need explaining first. Wren found she could breathe a little easier around a man who judged her only by whether her hands did the work right, and for four days, between resetting bones and inventorying bandages and teaching Tam how to properly clean a wound instead of just wrapping it and hoping, she let herself believe that quiet might actually be enough to build a life on.
Almost.
Tam attached himself to her within the first two days, the way young wolves eager to prove themselves sometimes attached to whoever would let them, and Wren, who understood exactly what it felt like to want a place to belong to, let him. He carried supplies for her without being asked, badgered her with questions about healing that had nothing to do with genuine curiosity and everything to do with wanting an excuse to keep talking, and told her, on the third evening, with the bluntness only a sixteen year old could manage without meaning any harm by it, that he'd heard the story from a border runner and didn't understand why the Alpha would give up a mate bond for a piece of paper.
"It's not really about the paper," Wren told him, surprising herself with how steady it came out. "It's about what happens to a lot of people if the paper stops existing."
"Still seems stupid," Tam said, with the total confidence of someone who had never once had to weigh three hundred lives against his own heart, and Wren, despite herself, had almost laughed.
Garrick ran a tighter post than the outpost's crumbling walls suggested, rotating watches through the night, drilling the younger wolves on the treaty line's landmarks until they could walk it blind. Wren respected him for it even as she watched exhaustion carve deeper lines into his face each night, because Thornwatch was twelve wolves trying to hold a border built for forty, and everyone there knew it, and nobody said it out loud because saying it out loud wouldn't fix the number.
It came back hardest at night, when the outpost went quiet and she lay on a cot too short for her with the wind finding every gap in the stone, and the space under her ribs would ache in a specific, directional way, like a compass needle straining toward a north it wasn't allowed to name. She never let herself finish the thought that came after. He's out there somewhere, and some part of me still knows exactly where.
On the fifth night, Tam didn't come back from patrol.
Garrick took four wolves out at midnight to search the border line, leaving the outpost thinner than Wren had ever seen it, every remaining wolf tense and listening in a way that made the wind sound louder than it was. Wren stayed behind at the clinic with her heart in her throat and her hands full of the same work, laying out bandages, boiling water, arranging what little they had, because it was the only thing she knew how to do with fear that had nowhere else to go. She caught herself, twice, standing still with a roll of gauze in her hands and no memory of picking it up, her mind somewhere out on the dark border line with a sixteen year old boy who talked too much and had attached himself to her like she was someone worth attaching to. She was still awake, alone, when she heard the horn.
Two short blasts. The Thornwatch signal for attack, need aid.
She grabbed the healer's bag without thinking and was out the door and running toward the gate before her mind had caught up with her legs, and that was how she ended up at the wall exactly when the fighting spilled through the broken section of it, six Ironridge wolves, larger and better fed than anything Blackthorn could field this far north, cutting through Garrick's returning patrol like they'd planned it that way, because they had.
Wren froze for exactly one second, which was one second too long, because a shape broke off from the fighting and came straight for her, not a random target, not chance, but straight for her, black furred, too broad in the shoulder, the same wolf that had watched her from the treeline three separate times since Blackthorn, and she understood, in the half second before it closed the distance, with a certainty that turned her blood to ice, that it hadn't been following her out of curiosity.
It had been waiting for the right moment to take her.
She didn't have time to run. She had time to drop the bag, grab the only weapon within reach, a length of iron fence post half buried in frozen mud, and swing it with everything her body had left, catching the wolf across the muzzle hard enough to make it flinch back a half step, buying herself one breath, no more, before it came at her again with its jaws already opening.
And two hundred miles south, in a study with a fire burned down to embers, Kade Ashworth came awake off the floor where he'd fallen asleep at his desk, gasping like he'd been drowning, both hands clutched to his own chest in the exact place his mate bond used to live before he'd severed it himself six days ago, because for one unbearable, impossible second, he had felt something tear through that dead space that shouldn't have been able to feel anything at all.
Fear. Raw, animal, absolute fear, that wasn't his.
"Wren," he said, out loud, to an empty room, and was on his feet and moving before he'd finished deciding to.
