The Beast in the Garden: A Modern Parable of Man and Nature by David Baron

... in which the author reconstructs an escalating series of cougar encounters with humans in Boulder, Colorado and discusses the unintended consequences of living with wildlife. The Beast in the Garden focuses on the reappearance of cougars in suburban Boulder in the late 1980's. Though it is nonfiction, the many separate sightings are cobbled together to form a narrative, and the book does have what could be called "main characters". The style reminded me very strongly of Jon Krakauer's writing in Under the Banner of Heaven.
