The Risky Rescue: Eric Luper

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. 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.
