"The Seven Chairs" by Lois Lowry.

All over the world baby girls levitate, unseen or disbelieved by their protectors. But with time and distraction, they all forget. All except one that is. Mary Katherine Maguire remembers, and practices, and masters her unique ability to "rise up" as she puts it. Written with the simplicity and beauty of a parable, this is a lovely story about the empowerment of women.
