The Demon's Lexicon by Sarah Rees Brennan

I just finished it. Kinda spoiler-ish review follows. No major plot points that the back of the book doesn't already have I guess. I liked it. I'm buying the next one when it comes out. I got mine on friday even though it's not supposed to be out yet but if you order it at bookshops here you can get it. Go figure.
The author's journal is sarahtales .
( And you felt what you really are is a christmas tree with too much tinsel. Huh. )
