"From the author of Raft of Stars comes an epic novel of adventure and river rafting, following a couple whose future depends on finding a way to navigate the changing currents of family, community, and the river itself"--

When suspicious deaths befall a whitewater rafting expedition through Cataract Canyon in Canyonlands National Park, archaeologist Chuck Bender and his family recognize evil intent lies behind the tragedies. They must risk their lives and act before the murderer makes an already deadly journey on the Colorado River through Utah's red rock wilderness even deadlier--or turns on them instead.

When a dam fails and rushing waters sweep away their adult supervisors, five middle schoolers on a white-water rafting adventure are left alone with few supplies and the opportunity to forge powerful bonds as well as develop dangerous disagreements.
