As for the story development around that, I found it slightly depressive with Michael's alterations from the vampire virus and his trouble over developing a kink for bites during sex. As well as hearing about Bill's past and his impressions when he was alive and Catholic. Everything in this story just painted a bleak image of the two of them aimlessly wandering, while Michael might yet become a vampire.
I appreciated the alternate pov from one story to the next but now I find it impairing as it's difficult to understand the characters' thoughts. I'd give this 2.5 stars. Not sure if I want to continue reading the series.
