What if the girl in your mirror wasn't a reflection - but someone trapped behind the glass, watching, learning, waiting?

Nora Lane is a social worker who has spent her life saving children from the kind of abuse she survived. But when she sees a strange young girl staring at her from inside a bathroom mirror - a pale child with dark eyes and a white dress - Nora becomes the target of something far older, lonelier, and more desperate than a haunting.

At first the sightings are fleeting. A handprint on the glass. A figure standing behind her reflection. Lips forming silent words:

Help me.
Let me out.

As the phenomenon spreads across the city and thousands begin seeing the same girl in every reflective surface, Nora discovers the truth: the child is Eleanor Marsh, an abused girl who vanished in 1962 after escaping through a mirror into a dead, silent world known only as the quiet place.

Nora becomes the only person who can communicate with her - and the only one the girl believes can free her. But something else lives in the quiet place. Something that has been feeding on Eleanor's fear for sixty years. Something hungry enough to push through the thin membrane between worlds.

To save Eleanor - and the city - Nora must confront her own past, face the memories she's buried all her life, and choose whether to save the girl behind the glass... or take her place.

A haunting, emotional, slow-burn horror novel about trauma, identity, sacrifice, and the monsters we inherit.
Perfect for fans of Paul Tremblay, Josh Malerman, and The Haunting of Hill House.
