The next three months are going to be a whirlwind for writer Seth Grahame-Smith. On April 10, the Pride and Prejudice and Zombies author’s next foray into genre-tweaked revisionist fiction, Unholy Night — about the Three Kings of the Nativity — arrives in bookstores. On May 11, his big screen version of the beloved horror soap opera Dark Shadows, directed by Tim Burton, hits theaters. And on June 22, Grahame-Smith’s adaptation of his hit novel Abraham Lincoln: Vampire Hunter, with Wanted director Timur Bekmambetov, will open.
