Cinder

Sucked me in right from the start, although I'm not quite sure why; possibly Cinder's sarcastic streak, maybe the creative insertions from the traditional tale, the rapid pace certainly helped and some pretty believable fantasy world-building didn't hurt what was a marvelously innovative take on Cinderella. My only complaint is that the plot arc followed the fairy tale too closely, resulting in ending foretelling; there's probably no way to avoid this without going completely off-tale, though.
