Vanessa Adler isn't so sure she really belongs at the School of American Ballet. But dance runs in her family. It's been a part of her life for as long as she can remember. Her grandmother and mother were prima ballerinas, and her older sister Margaret was, too. That is, until Margaret mysteriously disappeared from school three years ago. Vanessa is heir to the family's gift and the only person who can fulfill her sister's destiny. She has no choice. But she never could have guessed how dangerous the school is. The infamous choreographer, Josef, isn't just ruthless with his pupils, he guards a sinister secret, one in which the school's dancers-prized for their beauty, grace, and discipline-become pawns in a world of dark, deadly demons.
