I really enjoyed this book - it was funnier and wittier than I expected. My only gripe is that sometimes the wit/humor was heavy-handed and sort of distracting. Sarah Rees Brennan obviously has a fantastic sense of humor, but sometimes I wish she had used that sense of humor a bit more sparingly. There were times when I wanted the characters to stop making jokes about everything and just speak plainly. Overall, though, the author managed to create an enjoyably quirky and intriguing mystery.
