Loner, military brat Grace Artemis Halsted is moving again, this time for her senior year at a high school in Northern Virginia: Mean Girl Capitol of the World. Not a problem. She couldn't care less about the six-pack of perfectly styled messy bun-wearing divas or the prima donna on her elite lacrosse club team. She's learned the secret to success in chess and lacrosse is to control the center of the board.
Meet the quirky posse of croquet-playing computer nerds, artists, theater geeks, and a gorgeous out-of-her-league crush who help Gracie maneuver rowdy crowded hallways and turf war fields while dodging a manipulative rival, exposing an elusive cyber bully, and avoiding her recurring nightmare come-to-life nemesis - the whistling, serial-killer vampire custodian.
