The Unbecoming of Mara Dyer

The Unbecoming of Mara Dyer  - Michelle Hodkin

For the most part, this book kept me intrigued and wanting to know what happened next.
But I never had any idea what was going on. Right till the end of the book, I was still trying to figure out what genre it fits in. I still don't know.
I suppose it helps you to connect with the characters, since you're on the same level of confusion as they are. But seriously. Are they ghosts? Are they just crazy? Are they some sort of supernatural creatures? I swear at one point I thought they were werewolves. (Spoiler, they're not.)
Lets address the one thing I understood: The Romance. Egh. It was annoying, really really annoying. I kept expecting Noah to be some evil scientist or something. (I don't know man)
Not a clue where the series is headed and I'm not sure I want to put my brain through the struggle of trying to understand book 2. However if I am in the mood for it, I'll give it a go.
