Caught in a sudden Montana blizzard, Lockwood Linden takes refuge at his cousin Heath's ranch, a decaying house with walls of rot and silence, land that stretches for miles. But safety is an illusion.

From the dead orchard, a figure charges toward him-shifting into a monstrous dog before Heath drags Lockwood inside and bolts the door. And upstairs, in a room meant for rest, something begins to knock on the glass: a boy with yellow eyes, staring in from the storm.

Now Lockwood must uncover the truth about his cousin's home and the unspeakable secret Heath has unleashed.

Can Lockwood escape the secret festering inside Heath's walls, or will the blizzard claim more than just his body?
