Now you have to remember that this is a middle grade book and I am going to say that it would probably be more enjoyed by the younger middle graders (8-10). I also think it is more fitting for boys than girls but I think both can enjoy it. Nathan Abercrombie, was in a accident with some chemicals that left him dead. He doesn't have to breathe, he has no heart beat, he has no need to sleep. His best friend calls him a zombie, but Nathan doesn't really like that term. The cool thing about being dead is you can stay up all night, but bad thing is that when you break something it breaks off of you. Nathan has some glue that is specially made to put him back together when he breaks.
BUM (Bureau of Useful Misadventures) knows that Nathan is a half dead zombie and they want to use him in their organization. Meanwhile, Nathan's gym teacher thinks he needs to toughing them up, but Nathan's just worried about losing a body part in the process.
Nathan thinks it would be cool to be a spy but when he learns somethings about BUM he is not sure if they are the good guys or the bad guys.
Overall, I thought this was a cute book, for me it was a fast read. I thought it was funny in parts and would recommend it to anyone who has young readers. It has all the fun elements of a kids book, robot squirells, lots of talk about farting, and one very gaseous mess due to a half dead zombie eating chicken wings.
