Ren Hopper is a park ranger in Yellowstone, still carrying the death of his wife, and his job is mostly managing tourists who get too close to the animals. His friend Hilly is a wolf biologist whom the anti-wolf faction in the surrounding valleys would like gone. Then she turns up caught in an illegal leghold trap set for her, and Ren starts asking questions that the county, the poachers, and his own bosses all want him to stop asking. Heller writes fly fishing and mountain weather better than the plot mechanics, and the wolf-reintroduction politics are drawn straight from life.
