The White Tower — Cathryn Constable

When Livy's accepted at Temple College, an exclusive school for the most gifted students, no one is more surprised than her. After all, she doesn't think she's very smart at all! But she does have a secret that sets her apart from everyone else...

Recently, Livy can't take her eyes off the sky nor stop her heels rising off the ground. And once at Temple, though busy with new friends and classes, she can't resist climbing out onto the roof. For next to the ancient statue that guards the mysterious white tower, Livy starts to have the strangest dream that she can fly.

But her dreams are more real than she thinks. And her behavior has been noticed by others, for whom the ability to defy gravity is a possible reality...one that they'll stop at nothing to use for their own ends. It's a race against time to discover that most dangerous of secrets--will Livy survive it?
