Elyse Harmon spends her days in a therapist's office, grieving the loss of her husband Jack-and the part of herself that died with him. Once an artist, she can no longer bring herself to paint, her creativity drained by grief and by a truth she has buried too deep to face.

When night falls, that grief opens a door into another world-one where shadows stretch too far, the sky bruises black, and monsters that were once men feast on the remnants of humanity. Whispers slither through the air, promising salvation through surrender.

The line between home and the broken world is thinning. Now terror hunts her, pressing beneath her skin and warping her thoughts. As her two worlds begin to collide, Elyse must confront the secret she's tried to forget-or risk losing not just her sanity, but the fragile life she has left.
