Every girl in Hollow Bend gets one night to become a woman. Eleven of them never came back to explain what that meant. Wren Ashworth has twenty-four hours left. She's spent her whole life memorizing the names carved into the chapel wall — girls who walked into Hollow Wood the night before their eighteenth birthday and came back quiet, changed, wearing a ring of white bone no one asks about. That's the Rite of Threshold. That's what "growing up" costs in Hollow Bend. Then a stranger walks out of the tree line asking about an aunt the whole village has agreed to forget, and Wren's mother finally tells her the truth she's been hiding for seventeen years: the debt isn't new. It's not even Wren's. It's her mother's — paid forward, quietly, the night Delia Ashworth was too afraid to die. The thing in the woods doesn't want a sacrifice. It wants a bride. And it has already decided which one. Wren has one night to fall in love, break a two-hundred-year-old bargain, and figure out what "becoming a woman" means when nobody in her life has ever been allowed to say it honestly — before the woods stop waiting and come collect what they're owed. Tomorrow, she becomes a woman. Whether she gets a say in what kind is the only question left.

Five years ago, Alpha Kane Ashworth stood in front of his entire pack and rejected the woman fate had chosen for him. He called her weak. He called the bond a mistake. He watched her walk away and told himself it was mercy. He lied. Wren Calloway rebuilt her life far from wolves, far from packs, far from the humiliation that still wakes her at 3 a.m. She doesn't dream about him anymore. She tells herself that too. But Ironwood is dying without its Luna, and a rival Alpha is circling the wreckage. The only way to save the pack Kane swore to protect is the one thing he swore he'd never ask for again — Wren, back at his side, bond reinstated, whether she forgives him or not. She didn't come back for him. She came back to prove she doesn't need him. He has five years of guilt and one impossible truth to confess: the rejection was never about her. It was the only way he knew how to keep her alive. Now they're out of time to pretend otherwise.
