A rustic log cabin, high on a bluff above the Missouri River. A hidden cave. Buried guilt. Dangerous strangers on the Katy Trail. Rose Carter left her family's cabin behind, years ago, for a big house and a high-powered job in town. When her world falls apart, she's drawn back to the cabin and the land she could never bear to sell. But the cabin she thought was abandoned is being used, and watched by others. And none of them want Rose poking her nose into the secrets on Carter's Crag. As her life spirals out of control, and her husband becomes increasingly distant, Rose starts to wonder if someone knows what happened that night, the night she's kept buried for so many years Forced to draw on reserves of physical strength and resolve she didn't know she had, Rose fights to stay alive tumbling through the muddy water of the Missouri River, alone in a dark cave, and deep in the moldering ruin of Renz Prison.
