Maybe you've seen the movie
Scott Pilgrim Vs. the World that was based on this series or maybe you haven't. Either way, this is worth a look. I should also mention that this is a graphic novel (with some manga influences).
Scott Pilgrim is 23 years old. He's between jobs and plays in a band. Oh, and he's dating a high schooler (named Knives Chau). Whether that's cool or not depends on which of his friends you ask. It doesn't matter for long because Scott meets Ramona. At first, he just sees her in the library, and then he lamely tries to talk to her at a party. For Scott to be Ramona's boyfriend, he must defeat her seven evil ex boyfriends. Defeating them is like winning a video game (really- its like Scott becomes a part of a video game). Ramona has dated some surprising people (an action movie star, a rock guitarist). Scott has also dated some interesting girls that he must also deal with. For awhile, Scott's life is pretty messed up.
Of the graphic novels I have read recently, this is my favorite. It is funny and has great characters. There are six volumes and (like a lot of graphic novels) is a quick read.
