I would give this book a solid 3 1/2 stars. I loved the main characters, Manny & Harlan, and their sidekicks Elsa & Ricky and the story was very engaging from the start. The pacing was great and it was a great page-turner. However, I found the ending a bit lacking. I understand the message the author was conveying, but there were a couple of loops that just didn't feel closed to me. But all in all it was an enjoyable read.
