While most readers will know that Abby isn't really a vampire, they will still enjoy this playful romp with the Crimebiters. The best part of the book is the way that the friends work together. Daisy may be popular, Irwin may be a bit of a nerd, and Baxter's checkered past as a bully still crops up from time to time, but the children all genuinely like each other and work well together. There are some very realistic dynamics portrayed-- the boys are surprised when Daisy becomes a cheerleader, and neither Irwin nor Jimmy are happy when she seems interested in a boy who is not either of them. Daisy takes over the presidency of the Crimebiters, and wants to move the meetings to a better location, which Jimmy doesn't like until he realizes it involves homemade ice cream sandwiches. My favorite part was when Irwin decided to be a cheerleader, and when he gets flak about him, he gets support not only from his friends but from an unlikely source as well.
Working a comics convention into a book is always fun, and the author is especially nice to Jimmy. Evans' sons actions are a bit over the top, but ultimately understandable, and the resolution is satisfactory. As always, Jimmy's parents are supportive of his actions and accompany him on this trip, even though they are a bit disappointed about the incident with the cafeteria lady.
Stower's illustrations are a nice touch, and their inclusion makes it easy to hand this book to readers who have read all of the notebook novels available and are able to move onto books with slightly more text. Hand this series to fans of clue oriented mysteries like the Hardy Boys or Ron Roy's various beginning chapter books, and make sure they've read the first three books in this series: My Dog is Better Than Your Dog, It's a Doggy Dog World and Dog Day Afterschool.
