The lost kids

"Just a few weeks ago, Wylie Dalton was living on magical Minor Island where nobody ages past seventeen, and in love with Phinn, the island's leader. Now, her home is a creaky old boat where she's joined a ragtag group of cast-offs from the island, all dead-set on getting revenge on Phinn for betraying them. But when the Lost Kids invade their former paradise, they're stunned to find that their once-secret island is no longer so secret, and that a much bigger enemy is gunning for Phinn... and all the Minor Island kids"--Back cover.
