This is the 3rd of 3 books about Secret Agent Boo. My soon-to-be-8-year-old son loved this, and the first 2, books. There are comic book style pages interspersed throughout the story. These pages are part of the story and make it REALLY fun to read. These books would be especially great for reluctant readers because the comic book pages give the reader a short break and because the topic (Secret agents) is fun. I highly recommend these books for girls and boys of many ages. My son and I both wish that this wasn't the end of the series! :(
