I've been avoiding the YA genre for a while after my recent hate reads of Twilight and Graceling. This one got off to a rocky start, leaving me a little worried tha it would follow in the footsteps of this new YA Mary Sue fad. Armstrong managed to save it, though, and did so admirably. I like that she wrote about teens who are really teens, with teen imperfections - hormones that haven't kicked in as much as they would have liked (no booBs!) or others that have kicked in too much (excellently referred to as 'puberty smackdown'). 
 The plot was good, it was pretty fast-paced and kept my attention. I wasn't so keen on the ending, but then I don't like cliffhangers.
