Louis Tomlinson is tired of playing games. Why live your life if it's not truly yours? He is told where to be and when, who to love and who not to love; he has no control anymore. A girlfriend of two years has suddenly vanished because the whole teenage world would rather see him in a make-believe relationship. Louis is done. It's time to start over, and be who he really wants to be.
Somewhere along the way, Wendy meets Pete, a spunky red-headed boy with a wild imagination. He soon finds himself facing a difficult task.

But Wendy isn't willing to let go of her much-needed role, and the suspicion that Pete may be hiding a huge secret prevents her from trusting him. Their lives just might be able to change with faith, trust, and a little pixie dust.
