I first saw this book in the "Recommended" section of People magazine (someone left a copy lying around the office). And last time I was at the library I happened to see it on the shelf while I was looking for a different book. So, the Romgi and I checked it out to read together.
It's definitely a fun book. The author does a really good job of capturing the middle school mentality. Even better, the drawings are hilarious. I guess the whole thing is adapted from a web comic. You can find the first few pages of the book at http://www.funbrain.com/.
Even though it was a quick read, it was well worth an hour of laughing. Read it...and remember why you're glad to not be in middle school anymore.
