Rachel Hawkin's Demonglass
I enjoyed Hex Hall quite a bit when it came out, and was pleased that it subverted a lot of the cliches of the genre. So when the sequel came out, of course I was excited to read it. And just when I was about to write it off as a cheesy and stupid follow-up, the end got all exciting and interesting! Still, most of it was cheesy, especially the parts involving forbidden romance. I'm not sure whether I'll read the third one. B/B-.
