Days away from completing her first year at Miss Castwell’s Institute for the Magical Instruction of Young Ladies, Changeling-born Sarah Smith might just get away with posing as an upper-class Guardian girl named Cassandra Reed. But strange visions of a Lightbourne destroyed by Miss Morton’s revenant army keep Sarah from enjoying her achievement. Plus, the Mother Book, Sarah’s one secret advantage and the ultimate entrée in Guardian society, suddenly stops revealing itself to her...putting her in a precarious position with the Guild.

Annaleigh lives a sheltered life at Highmoor with her sisters and their father and stepmother. Once there were 12, but loneliness fills the grand halls now that four of the girls' lives have been cut short. Disturbed by a series of ghostly visions, Annaleigh becomes increasingly suspicious that her sister's deaths were no accidents. The girls have been sneaking out every night to attend glittering balls, dancing until dawn in silk gowns and shimmering slippers, and Annaleigh isn't sure whether to try to stop them or to join their forbidden trysts.

Ava and Gen are best friends. Ava knows what she wants and has plans to achieve her goals. Gen...not so much. But no matter how annoying, dramatic, or utterly bananas a two a.m. rant might get - Ava has always been there for Gen, and Gen for Ava. But then, they graduated high school. Now, they're in the same time zone (although over 1,000 miles apart), and in the real world, and it's the worst, but they still have each other's support. For relationships. Questionable roommates. Internships. And whether or not it's a good idea to take in a feral cat.
