Blood Lure

District Park Ranger Anna Pigeon is sent to Waterton-Glacier International Peace Park, which straddles the border between Montana and Canada, on a cross-training assignment to study grizzly bears. She hikes the back country with bear researcher Joan Rand and a volatile, unpredictable teenage boy, looking for signs of bear.

On their second night out, the roles reverse. One of the animals comes looking for the group, and the people who set out to track it become the ones being hunted.

By daybreak the boy is missing and a camper has been found mutilated. Anna is shaken by more than the violence. The bond with the natural world that she has relied on all her life has inexplicably broken, and the wilderness she trusted now feels hostile.

The mystery, part of Nevada Barr's series about Anna Pigeon, moves from a slow, watchful trek through bear country into a search for a missing boy. Fear closes in on a woman who can no longer read the wild.
