I think I would have enjoyed this more, if there were less Simon Snow segments and pages of the fanfic. I love fanfic more than most, but i found myself skimming it. 
 Outwith that - I think Rainbow Rovell is proving to be a dab hand at writing secondary characters, perhaps even better at writing them than writing main characters. I didn't really warm to Cath for a while, although I did get her more as the story progressed. I loved Levi a lot (who doesn't?) and Cath's dad and Regan were all wonderful characters. The relationship between Cath and her trying to be independent twin sister was handled really well too. Nick...I think the Nick character and his motivations were obviously designed to contrast with Cath and her's (what is borrowing and what is stealing) but I never felt it was resolved. In fact, I felt like the whole book was left a bit too open ended. Maybe that was the point...the Freshman year being like a dog year thing...where a lot happens and not a lot is resolved, but still. 
 It was a good, quick read. The romance was sweet and made you smile and it made me think back to my own first few months at uni and everything that was going through my own head at that time, but beyond the superficial, I don't think it's a book I'm going to be itching to re-read, or even remember much beyond this reading.
