Some honeymoons end in divorce. This one might end in death.

Brie Greene married a stranger—at least, that's how it feels when Steven insists on honeymooning at a remote campground. Tightly wound and hypervigilant, Brie sees threats in every noise and shadow. She's spent years burying a past she refuses to name, and the backcountry feels like a trap designed just for her.

Then Steven vanishes during the night.

Some of the campers offer sympathy—too much sympathy. Others assume Brie's to blame. But Brie knows someone's lying. Someone knows where Steven is.

As a rockslide seals the campground and it becomes apparent that help won't be coming, Brie realizes this isn't about a missing husband. It's about her. It's always been about her.

She thought she knew what she was running from.

She was wrong.
