This is a Gossip Girl meets Gone Girl style thriller, set at a prestigious boarding school in New England. Of course, I couldn’t put it down. Charlie Calloway is 17 years old but her mother disappeared when she was only 7. The book explores the mystery behind her mother’s disappearance (everyone suspects her father), and her boarding school experience as she is tapped by “The A’s,” an exclusive secret society at her school. It’s a fun, fast read (told from the perspectives of Charlie, her mother Grace, and her father Alistair) with lots of twists.
