Deborah Harkness novel pits vampires against sorcerers in interspecies war

Warner Bros. is looking for witches and vampires, buying feature rights to adapt Deborah Harkness’ “A Discovery of Witches” and setting the project with Denise Di Novi and Allison Greenspan.

The story centers on a reluctant witch and a 1,500-year-old vampire. The witch — a direct descendant of the first woman executed in the Salem Witch trials — accidentally unlocks an enchanted manuscript and finds herself in a race to prevent an interspecies war.

Harkness, a professor of history at USC, is writing the story as a trilogy and the second novel, “Shadow of Night,” will be published by next year.

Matt Cherniss is overseeing for Warners.

Warner-based Di Novi is a producer on upcoming Steve Carell comedy “Crazy Stupid Love” and has produced a quartet of Nicholas Sparks film adaptations — “Message in a Bottle,” “A Walk to Remember,” “Nights in Rodanthe” and upcoming “The Lucky One,” starring Zac Efron. She’s also a producer on Warner’s “The Heist Society” with Drew Barrymore.

Harkness is repped by CAA.
