It happened on a Tuesday, which felt like an insult in its own small way. Wren had always assumed, if she ever thought about it at all, that anything strange in her life would have the decency to arrive on a day that felt significant.
She was three miles outside Hollow Creek, gathering yarrow along the tree line where it grew wild and stubborn between the roots of old oaks, when the world tilted sideways for exactly four seconds.
It started as a pressure behind her eyes, low and building, the kind of ache she might have blamed on too little sleep if it had not arrived so suddenly, so completely without warning. Then the hum she had grown used to over three years, the faint, directionless pull at the edges of sleep, surged up through her chest like something had reached in and yanked a cord taut.
She dropped the basket of yarrow. Her knees hit the dirt before she understood she was falling.
For four seconds, Wren Calloway saw something that was not there.
A line of trees, not the ones around her, older and darker, wrapped in a faint silver light that pulsed like a heartbeat. She could feel the shape of it without understanding what she was feeling, a boundary, ancient and vast, stretched thin somewhere far away and straining under a weight it was no longer strong enough to hold alone. Something was pressing against it from outside. Testing it. Looking for the place where it would finally give.
And then, impossibly, she felt herself answer it.
Not with words. With something older than words, some instinct buried so deep in her blood that she had never once suspected it was there, rising up through her chest and out through her skin like heat radiating off a stone left too long in the sun. The silver light in her vision brightened, steadied, held.
The pressure vanished as suddenly as it had come.
Wren knelt in the dirt at the edge of the tree line, gasping, her hands pressed flat against the cold ground as though the earth itself might tell her what had just happened. Her heart hammered against her ribs. Sweat had broken out along her hairline despite the cool morning air.
She had no name for what had just happened. She only knew, with a certainty that settled into her bones like something remembered rather than something learned, that whatever she had just done had cost her something.
She realized it slowly, the way a person realizes a tooth has gone missing only when their tongue finds the gap. She reached for a memory, something small and specific, the sound of her mother's voice, which Marlowe had once described to her in careful detail years ago, the particular warmth of it, the way she used to hum while she worked.
The memory was gone.
Not faded. Not blurred with time the way old memories sometimes soften at the edges. Gone, cleanly, as though someone had reached into her mind with careful hands and lifted it out entire, leaving behind only the knowledge that something had once been there and was not there any longer.
Wren sat very still in the dirt, yarrow scattered around her, and did not cry, because crying required understanding what exactly she had lost, and she was still too far inside the shock of it to grieve properly.
She thought of the letters. All those small, careful mentions to Marlowe over the years, the pull she felt at the edges of sleep, the hum beneath her skin that never quite went away. She had called it grief. She had called it a scar. She had never once considered that it might be something with a purpose, something that had been waiting three years for a moment exactly like this one.
Something out there needed her. Something far away, wrapped in silver light and strained past its limits, had reached for her without permission and taken a piece of her mother's voice as payment for whatever help she had just given it.
She did not know it was Thornhaven's border. She did not know that two hundred miles north, an enemy pack's scouts had just been repelled from a breach point they had spent weeks probing, thrown back by a surge of power the border patrol could not explain and Grayson Ashford, riding hard toward Hollow Creek with three days of road behind him and two more ahead, would not learn about until he arrived to find his own beta half convinced the wards had somehow healed themselves.
She only knew that something in her had answered a call she never consented to receive, and that it had taken her mother's voice as the price.
She gathered her scattered yarrow with shaking hands, walked the three miles back to Hollow Creek in a daze, and did not sleep that night, staring instead at the cracked ceiling of her loft bed and turning the strange, silver shaped hollow of loss over and over in her mind, searching for a name that would not come.
Two days later, a stranger rode into Hollow Creek asking after a healer with dark hair and no family, and Wren felt the hum beneath her skin surge for the second time in her life, this time for an entirely different reason.
