Grizzly Confidential: An Astounding Journey into the Secret Life of North America’s Most Fearsome Predator

Kevin Grange, a former paramedic and park ranger at Yellowstone and Grand Teton, investigates grizzly bears (Ursus Arctos) across North America. His journey spans from the Tetons to a mist-covered island inhabited by large bears, the Bear Center at Washington State University—where researchers study hibernation's potential applications for treating diabetes, heart disease, and obesity—and into illegal wildlife trafficking and black markets dealing in bear bile. Grange encounters biologists and activists whose work challenges his previous understanding of grizzlies. His research culminates on a remote section of the Alaskan Peninsula, where humans and brown bears have coexisted peacefully for fifty years amid the largest concentration of brown bears on the planet. The book combines science and travel narrative, exploring both grizzly behavior and the people dedicated to their protection. It addresses bear conservation while documenting encounters with the species and examining the wildlife trade's darker aspects.
