3.5 Stars. 
 It's Ally Carter, so obviously it was good. Although I'm not sure that I love Gracie (the main character), because I'm never sure if I can trust her judgement or not. But I did trust her more in this book; in fact, all the characters grew on me. And the climax of the book was fabulous, although the ending felt a little cliche. But I'll definitely read the next book, because it's Ally Carter.
