Thirteen-year-old genius Grady Jacobs thinks junior high is a snore. His radical science experiments have earned him plenty of national awards, but not a lot of friends. So when an invitation comes to join the famous scientist, Dr. Carter, in the Brazilian rain forest, Grady is on the next plane to the Amazon. But Grady's ultimate field trip turns ultimately awful when he discovers what Dr. Carter is really up to: he isn't there to save the rain forest -- he is there to destroy it! Can one eight-grade science whiz put a stop to Dr. Carter's evil plans? He can when he is joined by the Urah-Wau tribe of Indians and a supernatural power that no amount of science can ever explain.
