I'm not surprised I really liked this one. The description pulled me in and I knew I had to read it. I haven't read the book it was based on, so I have no point of reference for that part of the story, but I was pulled in and intrigued with the story and the characters.
What I didn't expect was to get a story from both girl's point of view. Normally, in a story like this, I prefer just the one point of view. But the way the author has written the story, it adds to the mystery instead of takes away, which I really loved. The more I read the more I really wanted to know what the heck was going on.
I liked the darkness. I don't find many YA books, that aren't dystopian, that seem to be on the dark side. It has a gothic feel that even the reader can get chills from. It wasn't over the top and it didn't feel like something that could never happen. Which makes for a very good story.
I'd suggest more mature YA audiences for this one, but it is definitely worth waiting for and picking up!
