HOOT

With a Florida setting and proenvironment, antidevelopment message, Hiaasen (Sick Puppy) returns to familiar turf for his first novel for young readers. Characteristically quirky characters and comic twists will surely gain the author new fans, though their attention may wander during his narrative's intermittently protracted focus on several adults, among them a policeman and the manager of a construction site for a new franchise of a pancake restaurant chain. Both men are on a quest to discover who is sabotaging the site at night, including such pranks as uprooting survey stakes, spray-painting the police cruiser's windows while the officer sleeps within and filling the portable potties with alligators. The story's most intriguing character is the boy behind the mischief, a runaway on a mission to protect the miniature owls that live in burrows underneath the site. Roy, who has recently moved to Florida from Montana, befriends the homeless boy (nicknamed Mullet Fingers) and takes up his cause, as does the runaway's stepsister. Though readers will have few doubts about the success of the kids' campaign, several suspenseful scenes build to the denouement involving the sitcom-like unraveling of a muckity-muck at the pancake house. These, along with dollops of humor, help make the novel quite a hoot indeed. Ages 10-up. (Sept.)
