The Neverland Wars, no. 1

Magic can do a lot—give you flight, show you mermaids, help you taste the stars, and... solve the budget crisis? That's what the grown-ups will do with it if they ever make it to Neverland to steal its magic and bring their children home.
However, Gwen doesn't know this. She's just a sixteen-year-old girl with a place on the debate team and a powerful crush on Jay, the soon-to-be homecoming king. She doesn't know her little sister could actually run away with Peter Pan, or that she might have to chase after her to bring her home safe. Gwen will find out though—and when she does, she'll discover she's in the middle of a looming war between Neverland and reality.
She'll be out of place as a teenager in Neverland, but she won't be the only one. Peter Pan's constant treks back to the mainland have slowly aged him into adolescence as well. Soon, Gwen will have to decide whether she's going to join impish, playful Peter in his fight for eternal youth... or if she's going to scramble back to reality in time for the homecoming dance.
