Book excerpt: Life at St. Agatha's School for Girls is anything but a fairy tale. With ratty blankets and a torturous device called the box, Eliza is desperate to escape. When she attempts to leave the school with her best friend, Millie, they discover something in the Louisiana swamps that may be even more dangerous than the orphanage—a world of silver-and-black fairies. But Eliza doesn't trust the sparkling beauties, and she’ll do anything to protect Millie. The only problem is once Eliza remembers her own terrible secret, it will be impossible to forget.
