One year after a random shooting changed their family forever, Nora and her father are exploring a slot canyon deep in the Arizona desert, hoping it will help them find peace. Nora longs for things to go back to normal, like they were when her mother was still alive, while her father keeps them isolated in fear of other people. But when they reach the bottom of the canyon, the unthinkable happens: A flash flood rips across their path, sweeping away Nora's father and all of their supplies.

Suddenly, Nora finds herself lost and alone in the desert, facing dehydration, venomous scorpions, deadly snakes, and, worst of all, the Beast who has terrorized her dreams for the past year. If Nora is going to save herself and her father, she must conquer her fears, defeat the Beast, and find the courage to live her new life.
