Twelve-year-old Rachel gets more than she bargained for when her dad's scientist friend leaves her with a mysterious baby chimp named Friday. But when the scientist suddenly disappears under strange circumstances, Rachel realizes there's a big secret—and maybe some real trouble—waiting to be uncovered.
