What a great concept! I thoroughly enjoyed it at the beginning, then the middle portion dragged on and got boring for me. Maybe the fact that I was tired and sleepy contributed to my not-so-positive reaction regarding the mid-portion of the book. As it neared the ending tho, the thrill ride picked up its pace again.
The love triangle reminds me of A.G. Howard's Splintered cast: Alice, Jeb and Morpheus. And with that said, I am going for the sort of evil guy like Morpheus -- Cole. I just love this character. And I feel sad sensing how he would probably be receiving the negative end in the next 2 books. :/
