To be honest, I had no idea what this book was really about. It's been on my TRP for such a long time ... I guess I just liked the cover (I'm a slut for nice covers ... yes I'm that shallow) 
 I gotta say, I was pleasantly surprised that Rowell managed to capture this huge thing that is fandoms. I mean, not all of us write fanfictions, but it was nice to see us portrayed positively for once. 
 This is the first book I read by Rainbow Rowell, and I loved it. It was cute, it was quirky. I liked the main protag and it didn't focus on the love story alone. Cath was interested in other things besides Levi, I especially loved her relationship with her dad and roommate. Reagan. Rowell also showed that having a twin sister (or a sister in general .. or sisters in my case) is not always easy. You always get compared to each other and most of the time, one is overshadowed by the other. 
 There were also some sprinkles of drama with Cath's mother and the mental health of her father (I don't feel right talking about this because I don't know if it's portrayed the right way or not). 
 What I also loved were the little bits of Cath's fanfiction and the original story they were based on .. that were added to the actual story. It made me want to read more about Simon and Baz (I'm kind of in love with Baz). It shows us, how much the stories of other people mean to us and how we don't want them to end and/or leave their world. (I think it was supposed to be like a "synonym" for Harry Potter?) 
 To sum up, the story is lovely and I'm certainly going to read more by that author. (I actually pre-ordered Carry On)
