This is as much alternate history as horror but I want to nominate
Anno Dracula by Kim Newman. The book tells us what might have happened if the heroes of Bram Stoker's Dracula had failed and the Count had succeeded in relocating to England. It would be a fun read especially since Dracula was a previous book club selection.

Amazon.com Review
As Nina Auerbach writes in the New York Times, " Stephen King assumes we hate vampires; Anne Rice makes it safe to love them, because they hate themselves. Kim Newman suspects that most of us live with them . . . . Anno Dracula is the definitive account of that post-modern species, the self-obsessed undead."
In this first of what looks to be an excellent series, Victorian England has vampires at every level of society, especially the higher ones, and they engage in incessant intrigue, power games, and casual oppression of the weak--activities, as we know, that are all too human. Numerous characters from literature and from history appear in both major and cameo roles. Spectacular fight scenes, stormy politics, and a serial vampire killer keep the action lively. A scholarly bibliography is included.
From Publishers Weekly
