The latest entry in the bestselling series featuring Anna Pigeon. Straddling the border between Montana and Canada lies the Waterton-Glacier International Peace Park-Annarsquo;s home away from home when she is sent on a cross-training assignment to study grizzly bears. Along with bear researcher Joan Rand and a volatile, unpredictable teenage boy, Anna hikes the back country, seeking signs of bear. But the tables are turned on their second night out, when one of the beasts comes looking for them. Daybreak finds the boy missing, a camper mutilated, and Anna caught in a grip of fear, painfully aware that her lifelong bond with nature has inexplicably snappedhellip. District park ranger Anna Pigeon is forced to reexamine her "spiritual connection" to God's creatures when she works on a project that has her hanging out bloody lures to attract grizzly bears in Glacier National Park. Although she manages to snatch an occasional moment of solitary communion with nature, there's no time for meditation when a rampaging bear attacks the researchers' campsite.
