Query: A book I couldn't put down

I saw it on Amazon. I read the description and was like eh. But once I started reading I was hooked! THis was a book that was different than what I usually read but loved it. At times *spoilers* you have to really pay attention because it goes on a different route. It kept me reading and will be reading more from this author!
