Thirteen years ago, the girl Winter Evans loved vanished overnight.

Now a homicide detective in Colorado, Winter is called to the scene of a brutal murder. Standing among the witnesses is a woman she thought she'd never see again—a woman calling herself Constance.

Amy is alive.

Married. A mother. And pretending she has never met Winter.

As another body is discovered, Winter's investigation begins to unravel a trail leading back to an isolated Christian conversion program hidden in the mountains.

The girl she loved vanished into a world built on silence, obedience, and fear.

The deeper Winter digs, the more she realizes the murders aren't random.

They're a reckoning.
