Sebastian Craig and Isabella Bryne have been best friends for five years in the Neverland of academia, and that's where they're planning to stay. So when Bella's brother, Asa, offers them a rent-free summer in his gorgeous home before they move to their next college and degree, they jump at the chance. It looks like a good deal at first... but there's more to Asa than meets the eye, and Sebastian finds himself suddenly hip-deep in complicated, grown-up problems and the frightening, bemusing prospect of having a family that will miss him when he's gone.

When the best summer of his life finally ends, Sebastian has to make a difficult decision between staying in perpetual childhood forever, and facing adulthood—with all of its joys and fears. It seems that when Sebastian and Bella came up with a master plan for the future, they didn't count on Sebastian being bewitched by Bella's brother.
