Winner of two National Science Fairs for his work on plant life, thirteen-year-old Grady Jacobs isn’t exactly Mr. Popularity. While spending his summer with the famous botanist Dr. Phillip Carter trying to save the rain forest with a new species of super trees, Grady stumbles on a startling discovery: a system of sounds that enables him to control the movement of trees. Even as Grady discovers the tree language, he realizes that Carter’s super trees aren’t saving the rain forest – they’re killing it. But even with the help of the Urah-wau Indian tribe and the secret tree language, can Grady stop Carter’s super trees?
