I absolutely loved the dialog in this book. The first person narration by Jessie had me laughing out loud throughout the book. Yes, there is a lot of mystery and some really scary situations but she could always insert a wisecrack or sarcastic comment and lighten the moment. My husband even asked me what I was laughing about as I read the book. These were great characters and you came to care for them. I think I'm usually pretty good at seeing twists in a story but I didn't pick up on the truly evil character until the very end. I'm going to read the other books in this series.
