I wasn't expect something like this, the girl was somehow infected and is turning into a monster. Actually, it's in the name of the novel, but still, I wasn't expecting her to become a monster chased by society.
The real star in this book is the building of tension, as the chapter progress we are eager to see the outcome of a chase, but the author keeps teasing us.
It is a good reading for suspense reading, I recomend.
