3.5 stars. I enjoyed this book. Cassidy's style is funny with many humorous moments sprinkled throughout the story. I had trouble connecting with Marty at first, but as the story went on, I could relate easier. The villains identity was clear to me as well as the reason for his/her actions, but it was still a fun read getting to the end. I'm definitely going to read more in this series, especially since Nina was one of my favorite secondary characters.
