Let's admit it: when you're fangirl like me and you come across a book about another fangirl, you'll inevitably become a super picky reader. Because you know what being a fangirl means, what pros and what contra it brings, what emotion it involves, what kind of character it implies. Here's the reason why writing a novel on this theme can be pretty tricky. 
 I had high hopes considering how hyped where the other readers about "Fangirl", but from my point of view it wasn't exactly that good. 
 Yes, I could partially relate to Cath, but just marginally. I mean, she considers herself a fangirl but she actually is obsessed just about one single series and she doesn't care about anything else. 
 Moreover, even though maybe it was just my impression, I think that she's described as a stereotypical "nerd" or "bookworm", a kind of socially inept who doesn't know how to interact with people who are not on internet, a dorky person always locked up in their room speaking only with fictional characters. 
 Isn't it time to go over this type of idea? 
 The writing style wasn't bad, but in the end this story too is still focused more on the romance aspect rather that what being a fangirl really means. This is why, despite it being a quick and (relatively) light reading - due to a pretty depressing theme in the main character's backgroung - it's not something that will remain in my heart for many years to come.
