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. In this beautifully reimagined story by Cynthia Leitich Smith (Muscogee Creek), Lily and Wendy embark on a high-flying journey of magic, adventure, and courage — and take their story back.
