I love, love, loved this one!!!! :D I really just adored Cath and I could sympathize with her social oddities....I have a few of them myself. I also absolutely loved the whole fanfic side of the story! I'm a huge fanfic reader myself so Fangirl completely clicked with me! It was fantastic and the characters and the story itself were just amazing...such a wonderful story! I NEED to read Rainbow's other books now!!!! :D And Levi...Levi, Levi, Levi! Love him! :D 
 I just reread this one as an audiobook, too, and it was just as amazing! I loved Cath, her stories, her friends, her family, and just everything! :D This one is still a big favourite of mine! :D
