A fast-paced locked-room mystery in Utah's awe-inspiring canyon lands.River guide Mandy Tanner and her fiancé Rob Juarez, owners of RM Outdoor Adventures, are leading an off-season rafting and climbing trip on the Colorado River. The unfamiliar topography and a lecherous local climbing guide have Mandy on edge - but that's nothing compared to the trouble the clients bring. When a young man is found dead, everyone on the trip is a suspect. Since there's no way out of the Colorado River's steep canyons, it's up to Mandy and Rob to solve the mystery before the murderer strikes again.
