I really enjoyed this book. I read it in about 3.5 hours. I really liked all of the characters, but the nickname of Fee for Mary Francis 'Frannie' Cavanaugh didn't really work for me. The love triangle was a good one. (view spoiler)[ However, it was really stacked against Gabe from the beginning. I mean what teenage girl is going to pick the totally hot guy that she can't make out with, over the one that she can make out with? Poor Gabe definitely drew the short straw. (hide spoiler)] 
 I liked the way the book was written, with the changing first person POV. It seemed to add to the story more than detract from it, but because it was an alternating POV, it seems like we missed out on a lot of character development. For instance, Frannie mentions that she enjoys Luc arguing with the history teacher, but we only see one brief snippet of that even though it is supposed to occur every class period. 
 The plot seemed fairly straightforward. I don't remember thinking that there were any unexpected twists, but I still thought it was a fairly good read. I look forward to any upcoming sequels, because I really enjoyed the characters. A lot of the supporting cast really didn't get explored much, and so I'm hoping we'll get more interesting characters in the sequels. 
 There were a few places where it seemed as though the setting sort of changed without the characters moving. Classrooms suddenly to lockers and that sort of thing, but it wasn't really annoying enough to be more than a footnote. 
 All in all, I think this was a decent YA book, but I can't think of any reason why it needed to be a YA book. I think a lot more could have been done with it storywise had she not been a high school senior living at home with 4 sisters and her parents. The high school aspect really only seemed to serve as a plot point for introducing a plausible reason for her to be interacting with the two hot guys on a regular basis, and having her live at home facilitated her sisters and parents interrupting her with both boys, but mostly just when she was with Luc. There were a lot of things that were brought up that really didn't seem to be addressed fully, and that I was wishing had more description. 
 For a first novel, this book was a good one, and the characters that were fully described were very interesting. I hope to see more of the Gabriel character in the sequel I hope to see soon.
