Lily and Wendy have been best friends since they became stepsisters. But with their feuding parents planning to spend the summer apart, what will become of their family—and their friendship? Little do they know that a mysterious boy has been watching them from the oak tree outside their window. A boy who intends to take them away from home for good, to an island of wild animals, Merfolk, Fairies, and kidnapped children, to a sea of merfolk, pirates, and a giant crocodile. A boy who calls himself Peter Pan.
