Book excerpt: Richard Clark, the narrator of this sharp and sometimes madcap novel is nineteen--a drug-addicted, foul-mouthed, sex-crazed young man in Africa on a safari with his parents. Obviously, this is a mistake. As Richard smolders with resentment, he documents the trip in a series of journal entries that are funny, sad, and piercingly insightful. Juxtaposed with the hostile environment, the tense situation becomes explosive: with raw energy and acuity, somewhere between Hunter S. Thompson and David Sedaris, we see Mom going insane, Dad drinking compulsively, and Richard busy getting high on smuggled drugs. Anything can happen, and it does, in this family travelogue for the twenty-first century.
