This book series is actually very promising, with the story about 23 year old Scott Pilgrim whose dating 17 year old Chinese high schooler Knives Chau. However, Scott falls in love with Ramona Flowers, a mysterious pink-haired roller skater that skates through his dreams (no, literally, she roller skates through his dreams randomly). They start a relationship, but apparently Knives and Ramona aren't the only ones after Scott. Anyone mature enough to handle the content in this book will enjoy it a lot. That said, there's a lot of jokes about sexual stuff, like Scott's gay roommate, Wallace seducing other guys. Wallace and another guy make out, Knives throws herself on Scott and kisses him, Scott's band name is "Sex Bob-omb," and finally, Scott and Ramona kiss, make out, and eventually almost have sex (they still have clothes on). That one scene is about as mature as it gets. READ THIS BOOK NOW. You will not regret it.
