At St. Teresa’s Preparatory School for Girls in Providence, Rhode Island, rebellious senior class genius Jane Jarvis is worried about her best friend Allison Concord. Ally is lovable, but a little clueless, and badly in need of Jane’s help. She needs to get a freshman “sister” at the school’s annual Big-Little celebration. When Ally blows it (rather literally), Jane knows that they are in for a rough few weeks. She has no idea just how rough they will be. Strange things start happening in Providence. Then Ally begins to change. She loses the awkwardness that Jane has always known and loved and becomes the model of cool. Things don’t go as well for Jane, and she soon winds up facing the threat of expulsion and ruin. But these are only the beginnings of much bigger problems. Jane’s life is about to get much worse. Ally claims that she sold her soul, and Jane throws herself on the line to get it back. But this battle is big. A crowd of strangers is about to descend on Providence, and they’re not there to go on a campus tour of Brown.
