The Historian, Elizabeth Kostova

"...The Historian is the story of a young woman plunged into a labyrinth where the secrets of her family's past connect to an inconceivable evil: the dark fifteenth-century reign of Vlad the Impaler and a time-defying pact that may have kept his awful work alive through the ages. The search for the truth becomes an adventure of monumental proportions, taking us from monasteries and dusty libraries to the capitals of Eastern Europe..."

Nothing in that said "vampires" and "Dracula" to me.

I mean, yes, I know Vlad the Impaler is the...inspiration, let's say, for Dracula, but nothing there indicated that's the route she was going. To me. Now, had I read the quoted blurbs, I wouldn't have been surprised when vampires made their appearance, but I never do. It's not like they're going to put ones that say the book sucks, or could be written better. So, I don't bother.

So, yeah, vampires.
