From School Library Journal Starred Review. Grade 5–8—Once again, Hiaasen has written an edge-of-the-seat eco-thriller. When their unpopular biology teacher goes missing in a suspicious fire during a field trip to the Black Vine Swamp, Nick and Marta don't buy the headmaster's excuse for her absence and decide to do some investigating of their own. Eco-avengers; an endangered, hunted panther; illegal pipelines in the Everglades; and an underachieving student with the nickname "Smoke" all play a part in this gripping novel. From the first sentence, readers will be hooked. The teens' dangerous detective work, with help from some unlikely sources, and the ethics of environmental awareness are well balanced. The emotion and personal changes that Nick goes through due to his father's injury in Iraq are on their own a worthy study of the struggles that military families are facing today. This well-written and smoothly plotted story, with fully realized characters, will certainly appeal to mystery lovers.—
