Lately, visitors to Mesa Verde have been bringing home more than photos--they're also carrying a strange, deadly disease. And once it strikes, park ranger Anna Pigeon must find the very human source of the evil wind.

Anna Pigeon has fled New York and her memories to find work as a ranger in the country’s national parks. In the remote backcountry of West Texas, however, she discovers murder and violence. Fellow park ranger Sheila Drury is mysteriously killed, presumably by a mountain lion. But the deep claw marks Anna finds across Drury’s throat and the paw prints surrounding the body are too perfect to be real.
