The girl who could fly

When homeschooled farm girl Piper McCloud reveals her ability to fly, she is quickly taken to a secret government facility to be trained with other exceptional children, but she soon realizes that something is very wrong and begins working with brilliant and wealthy Conrad to escape. Piper McCloud's ability to fly sets her apart from the other kids, so her mother sends her to an exclusive school for children with exceptional abilities, but even there she does not fit in with the other students.
