Walter Kirn lives in Montana where he works as a book critic. But he grew up in Minnesota, and so its not surpring his new novel "Thumbsucker" is set in the St Croix River Valley. Although it's probably not going to please the Minnesota Tourist board. Kirn's satirical view of rural Minnesota in the 1980's is a turbulant world of Miami Vice, Izod shirts and Mormons. In a town gone suburban, 14-year-old Justin, gives up thumbsucking his long-time security blanket, only to replace it with girls, cigarettes, booze and drugs. With adults too self-absored to care, Justin is forced to navigate the bizarre waters of adolesence alone.
