Fifteen-year-old Mia is not exactly thrilled when she gets the news that her parents are shipping her off to boarding school. It's not like she did anything that bad - all she did was wreck her dad's car and max out her step mum's credit cards. So, off she goes, from Chicago to Bard Academy, an exclusive prep school that treats troubled teenagers with a healthy dose of higher learning and old-fashioned discipline. But all is not what it seems at this educational institute, and Mia and her classmates soon discover that the teachers are actually ghosts, stuck in limbo, some of them famous authors who died before their time, including Virginia Woolf, Ernest Hemingway, and Charlotte Bronte. And what's even more disturbing is that not all the ghosts have good intentions. Mia and her friends must stop one evil instructor's plan to bring down the school - and the entire student body with it.
