The Historian

(from Wikipedia)

The Historian has been described as a combination of genres, including Gothic novel, adventure novel, detective fiction, travelogue, postmodern historical novel, epistolary epic, and historical thriller. Kostova was intent on writing a serious work of literature and saw herself as an inheritor of the Victorian style. Although based in part on Bram Stoker's Dracula, The Historian is not a horror novel, but rather an eerie tale.
