I want to make a confession, please don't hate me. Although I know of Rainbow Rowell, until a few days ago I hadn't read any of her novels. 
 I knew they were contemporary though (a genre I'm not usually fond of), so when Carry On started to be reviewed by everyone I thought it was contemporary too. It was only a few days ago when I read that it was a fantasy novel. That was enough for me, and without paying much attention to the plot summary I dove into it persuaded by the good ratings everyone was giving it. 
 5% into the book I thought something was wrong... I was reading HP with a twist. 
 I knew an author such as Rainbow Rowell wouldn't publish a fan fiction unless there was a reason for it... so I started to investigate and found out that Simon Snow's story is really a fan fiction written by the main character of her other novel, Fangirl. 
 "COOL" I thought 
 But what turned out to be an extremely interesting idea, it was also one of the things I disliked... BUT, it is also part of the uniqueness of the book and I really respect the originality of the concept. The thing is, the story REALLY has the feel of a fanfiction. 
 There are mentions of past events on Simon Snow's story but it feels as if you landed in the middle of a series and something is missing... BUT (this review has a lot of "but's") since I haven't read Fangirl, maybe I'm lacking part of the story, so I won't punish the book for it in the rating. 
 Besides the interesting concept, what made the book shine was the relationship between Baz and Simon. I think that without it the story would have felt flat! I loved their complicated relationship and would have liked more of it. 
 If there is a second book about Simon Snow after school I'll definitely read it!
