"This book hits like a summer squall and never lets up, a real-time, one-location doom machine that earns its place beside The Mist."

• Daniel Kraus, author of Whalefall

A sudden storm appears above an isolated farmhouse in rural Illinois, bringing with it a relentless and unnatural rain. A rain that eats away at everything it touches. A rain that turns people into monsters.

Trapped inside his crumbling home, a father must do everything he can to keep his family from falling apart. But the rain calls to them, and not everyone wants to stay inside.

Haunted by memories of loss, he must put aside his painful past and find a way to keep them all safe. But the rain shows no signs of stopping, and time is running out.
