In this emotionally complex novel, Ren Hopper, a park ranger at Yellowstone, finds himself exceeding his jurisdiction while trying to get to the bottom of the threats and sabotage escalating in the park. A beautifully written novel so evocative of the natural world that it will make you want to head for the forest ASAP, while also deeply compassionate and painfully human. This one's going on the keeper shelf next to Dog Stars.
