This is one of the best book series ever. I am in the target age group. i think that this story can be relatable at times, like when he is in school and is waiting for the bell to ring but, somethings i don't think some of the things he does could happen to a real family. They only thing i don't like about these books is Manny. Manny is Greg's younger brother and he is like two he is really small. In Cabin Fever he goes missing for like 2 days and no one tries to find him. :l The other thing is he is in middle school and there are like 15 books some are in the summer. I like this book series because it is the underdog that ends up having a good time
