** spoiler alert ** Overall, I liked. I went in expecting something akin to Stephen King's "Salem's Lot"--Which this is NOT--and ended up with a suped up urban fantasy instead. Wilson's vampires were clearly evil (a gigantic plus), but I didn't care for their bickering among themselves and their too-organized militaristic approach.
Wilson introduced a great sub-antagonist in Barrett, but did little with him which was somewhat disappointing. And Father Joe was an amazing lead character until he turned into Joseph and jumped onto the urb-fan express. Still, head and shoulders above what is passing for vampire fiction these days.
Finally, someone whose vampires aren't raging sex machines! I absolutely loved that Wilson's vampires were impotent and concentrated on one thing and one thing only: Blood. The best part of the book, in my opinion, was the opening scenes with Carole, especially the scene in the rectory when her fellow sister came back from the dead. That was tremendous.
