This book was quick and interesting and at times, fun. My only real problem with it was that it should have been longer. I really liked all of the characters and their relationships/friendships with each other, and I wish the book had been longer so that could be even more developed. But hopefully the rest of the series will add to this. My favorite character was Michael, though I also loved Lia. I also really loved the behavioral science concepts that were included in this book, especially because JLB is a psychologist. I took a behavioral science class last year so it was neat to see the concepts I learned about being discussed in realistic scenarios. Overall I really enjoyed this, and I'm going to read book 2 as soon as I can get my hands on it!
