The switching back and forth between the two viewpoint characters seemed to impose an artificial and hampering structure on the narrative. I think slipping in chapters from a third, or even a fourth, viewpoint character would have helped relieve the feeling I had of listening to a two note piano composition for three hours straight. Also, the pacing really dropped off a cliff at the start of the final quarter of the novel, and it took a while for it to pick back up. But, generally, this was a pretty entertaining read. It had enough inventive set pieces and action to keep me interested throughout. I liked the characters and the horror elements. I will likely pick up the other books in the series at some point in time. However, they are not at the top of my priority list.
