In the tenth novel in New York Times bestselling author Stuart Gibbs's FunJungle series, super sleuth Teddy Fitzroy is on the case to rescue an abducted young gorilla!

When a baby gorilla is stolen from an orphanage in Rwanda, Teddy, his parents, and an old family friend find themselves in a race against time to save it. Teddy has to piece together clues to figure out where the little ape is being taken while traveling through some of the most incredible--and dangerous--terrain in the world.

At the same time, he's long-distance consulting with Summer to help solve another mystery back at FunJungle. Between facing down lions on the Serengeti and chasing poachers through the bazaars of Zanzibar, will Teddy be able to find the baby gorilla before it's too late?
