This story revolves around a History professor and his daughter. The Professor, and his mentor Professor Rossi, stumble across ancient texts that seem to imply that Vlad Dracula didn't die in Wallachia. As they begin to delve further into this historical mystery, it begins to dawn on them that, perhaps, Dracula didn't "die" at all.
The story then takes on a strange journey through the halls of University libraries, to various countries from Hungary to Romania. All of this is to find where Dracula's actual tomb is. Along the way, as strange disappearances and strange events begin to occur, the intrepid heroes find that Dracula might still be alive and that vampires are real. This mystery will eventually lead them into a confrontation with the myth become reality.
Superbly written and impeccably researched (obviously the vampire stuff is fiction), there is a great deal of cool historical setting as Kostova really gives a wonderful view of the traditions and folklore of the Eastern Europeans. Sometimes the story is interspersed with letters that give further insight. Yet, this never loses the feel of a "horror" story.
If you're looking for a well written and superbly researched story about Dracula, then look no further. A great horror story and a great novel in general. Highly recommended if you're a fan of vampires or even just history.
