Commemorating twenty years since the wolf’s return to the American West, Howl explores passions and controversies surrounding nature’s most fascinating predator. Susan Imhoff Bird travels the West, journeying from her home in Salt Lake City, Utah, through Yellowstone and Montana. Along the way, she interviews ranchers and park personnel, wolf watchers, biologists, and families, uncovering a range of emotions—from admiration and reverence to vitriol and anxiety—toward wolves and all that they have come to signify.
