DNF = automatic 3 stars 
 Not the intended audience. I don't do well with a writing style that has multiple narrators, including the 'bad' guys. I enjoy it when it's the main characters, but I don't want to be in the head of every character. 
 Head-hopping, it always comes across as unfocused, giving away too much while taking away from the mystery of it all. There was no transitions from one narrator to the next within the same chapter. One sentence I was reading Dr. Alex, then the priest, then was in another's head in another country, sounding as if in another time. Whiplash. 
 I would just begin to connect with what was happening to one character, and then be thrust out into another's, where I didn't care one way or another. 
 Wooden, dry, and choppy, the writing style was not to my tastes
