The Historian, by Elizabeth Kostova

“A teenage American girl, living in 1972 Amsterdam, comes across an ancient book in the library of her widower father, a former historian and now a diplomat. The book, blank save for an illustration of a dragon and the word Drakulya, contains a cache of faded letters all addressed to “My dear and unfortunate reader.” Thus begins a search for the truth behind the myth of Dracula, a search that crosses continents as well as generations.”
