Between work and money concerns, did your big summer holiday plans somehow end in a sad little staycation? Let C.J. Box take you on an audio tour of Yellowstone National Park— murder, mystery and mountains included. The central figure here is Cody Hoyt, an angry, alcoholic Montana cop barely holding on to his sobriety. Worse, the body of his AA sponsor is found burned, and Cody's adored 17-year-old son is in danger. (Narrator Holter Graham conveys the demons, rage and parental love inside Cody.) Box, a best-selling mystery writer and Wyoming native, crafts a taut tale, but it's his details about the untamed flora and fauna — two-legged as well as four — that inhabit the wildness out West that hooks you.
