During a field trip to Black Vine Swamp, a suspicious “wildfire” breaks out, and much-feared and -reviled science teacher Mrs. Starch vanishes. The school gets a letter stating she is away on a “family emergency,” but no one believes that. Nick Waters and his friend Marta Gonzales are sure bad-boy Duane “Smoke” Scrod, Jr., is to blame for both fire and disappearance. However, there’s more to Duane, Mrs. Starch and the fire than Nick or Marta could ever imagine. This is Hiaasen Country, so the complications include a rare Florida panther, a crooked oil company, a tree-hugging Hayduke of a millionaire and a couple of well-meaning-but-not-as-swift-as-the-kids detectives. Hiaasen’s third outing for young readers might be a little slow in pacing and the character types might be recognizable to experienced readers, but fans of Hoot and Flush (2002, 2005) will not be disappointed by this funny, believable, environmentally friendly tween thriller.
