Here's a description of the series
taken from its Wikipedia page:
The Anno Dracula series by Kim Newman—named after Anno Dracula (1992), the series' first novel—is a work of fantasy depicting an alternate history in which the heroes of Bram Stoker's novel Dracula fail to stop Count Dracula's conquest of Great Britain, resulting in a world where vampires are common and increasingly dominant in society. While Dracula is a central figure in the events of the series, he is a minor character in the books themselves, and usually appears in only a few climactic pages of each book.
