I liked the premise of this book, and generally like Eoin Colfer's writing style and use of language, however, this book seemed to drag on for me. Not due to lack of action, there is constant danger and our heroes are never far from harm, but it just seemed like there were so many storylines that had to happen before we could put it all together and I just got tired of having new people introduced when I felt ready to wrap it up. I do think many kids would like it. There is definitely murder - it is called the Reluctant Assassin for a reason - and it seems to be mostly recommended for 12+. I have some mature 5th graders that I would feel comfortable sharing it with. Grade 6+. Listened to May, 2014.
