I absolutely loved this book. So much, it was difficult for me to put it down. Alas, I did put it down when it ended.
I'm sure I loved this book so much because I could relate to - not just the main character, but things in every character. The whole thing just sucked me right in and wouldn't release (or rather, I didn't release the book from my hands).
Basically I'd recommend this book to anyone that is a fangirl themselves. I think anyone who doesn't really understand the obsession behind being a fangirl would not enjoy it (although we all tend to have a little fangirl screaming inside of us.)
5 stars because now I'd love to pick up another one of Rowell's books!
