After a heated auction, Sony Pictures Entertainment paid seven figures for “The Historian,” Elizabeth Kostova’s upcoming first novel. Red Wagon partners Doug Wick and Lucy Fisher will produce. The novel, to be published on June 14, mixes history and mythology to re-create the world of Dracula and vampires. A decade in the works, the adventure tale centers around a young woman who searches Europe for her missing father, who took on the challenge of locating the grave of Vlad the Impaler (the bloodthirsty feudal lord who inspired Bram Stoker’s “Dracula”). Along the way, she comes across a slew of bloodsuckers who try to stop her.
