in this series, Diary of Wimpy Kid (not in the least because the main character's name is Greg.) I think it is very funny and is written very convincingly in the mindset of a teenager.
I was lucky enough to get my hands on an Advance Readers Copy, so this is an old review. This second book in the series puts Greg in a bad situation. His brother has been blackmailing him to do his every whim after he finds out one of Greg's most embarrassing secrets (yes, you find out what it is, and you'll be suprised). This book is probably the funniest book so far. The author really flexed his creative muscles on this one. I actually laughed out loud on this one, and I'm very hard to please. There are as many classic moments in here as the first one. If you liked the first one or are a sucker for the funnies in the paper, this one is definetly for you!
This book doesn't have any innapropriate words or subjects, but you can tell it was written for teens. It is suitable for all ages, but I think teens would "get it" more. Nonetheless, my nine-year-old neighbor loved it. Go figure.
