After a violent accident she can't fully remember, Gianna Vander Wal is shipped off to St. Elira's Institute by a father she barely knows and a stepmother who watches her too closely. Isolated on a windswept cliff and surrounded by whispers, the prestigious school pulses with secrets-students vanish, memories blur, and the walls seem to breathe. As Gianna digs deeper into the institute's grim history, she begins to question what's real, what's been erased... and whether she was sent here to heal-or disappear.
