The signal

Summary: Backpacking into the Wind River Mountains on their tenth annual trip, Mack and his wife, Vonnie, find the magnificent woods and stunning mountains of Wyoming full of ghosts and danger. Mack comes from a long line of ranchers, and his dedication to keeping the family land has led him into penury and a life of crime. Vonnie is a fiercely intelligent and headstrong woman who came west for love, only to have it stolen from her bit by bit. They've made the trip to say goodbye to each other, but as they navigate the trails they know so well, they come to understand the true nature of their wounds. And Mack has one more secret: he is receiving a tracking signal that will allow him to retrieve something that has fallen from the sky. It is a beacon that will lead them into a wood far darker than any they'd ever imagined.
