Book details for Thumbsucker
Like a mucked-up modern Huck Finn plying his own stream of consciousness, Justin drifts into weird scenes: a job at a gas station fated for torching, a visit by his mad Winnebago vagabond grandparents, a kidnapping caper to rescue a pothead infant from sinister hick parents, Grit and Munch. Chapter 4, about a Chippewa City debate meet and rather chaste orgy, is dazzling teen satire. Not that Thumbsucker is flawless: Justin's nurse mom is a vague character, his more vivid kid brother is inexplicably ignored, the satire of the Hazelden celeb rehab is lame, and, like Huck's, Justin's adventures sort of peter out instead of leading up to a slam-bang finale. The family's conversion to Mormonism seems arbitrary, though richly detailed, since Kirn was a small-town Mormon kid.
Flaws, schmaws. Thumbsucker is the truest book about adolescence I've read since This Boy's Life, and Kirn is some kind of comic genius. --Tim Appelo
