I loved it! One really cool thing about this series is that starting with this volume, there's a short description of each of the characters at the beginning of the book. The character list gets longer as we get introduced to more characters, plus there's a page devoted to the story so far. Also cool is the fact that there's instructions on how to Play Rich Man, Poor Man, which is mentioned a few times in volume 1, info about the year of the rat, fan art, and a sound effect index. 
 So, I really liked the artwork, which is really detailed. I love how even when the characters aren't talking, I still know what's going on and can tell what they're thinking. Scattered throught the book are notes from the author: some are "ultra special blah blah blahs" while others just random side notes where the author talks about video games she's playing or writes about the characters. 
 Rating: It gets a 5 out 5! The storyline is cool, there's really detailed illustrations and I love the random notes. Plus, the character list becomes important later in the series because we get introduced to more and more characters.
