The risky rescue

When Evan and Cleo sneak into the enchanted library at night they find that Locke has already forced his way into a book, and when they follow they find themselves in a plane that promptly crashes into the Amazon rainforest--and with the help of a boy named Gabriel, (and a friendly sloth) they have to survive the jungle and find the golden statue that is the next treasure in their quest before Locke gets his hands on it.
