The New York Times–bestselling children's fantasy series continues as the Girl Who Can Fly joins forces with a boy who's smarter than the average genius.

There is a prophecy.

It speaks of a girl who can fly and a boy who knows everything. The prophecy says that they have the power to bring about great change . . .

The boy is Conrad Harrington III. The girl is Piper McCloud. They need their talents now, more than ever, if they are to save the world—and themselves.

Victoria Forester does not disappoint in The Boy Who Knew Everything, the long-awaited sequel to New York Times–bestselling The Girl Who Could Fly, which Stephenie Meyer praised as "the oddest/sweetest mix of Little House on the Prairie and X-Men."
