Deborah Harkness (born 1965) is an American scholar, novelist and wine enthusiast, best known as a historian and as the author of the "All Souls" Trilogy, which consists of The New York Times best selling novel A Discovery of Witches and its sequels Shadow of Night and The Book of Life.
Born in 1965, Harkness grew up near Philadelphia, Pennsylvania, the daughter of an American-born father and a British-born mother. She is a graduate of Mount Holyoke College (B.A., 1986), Northwestern University (M.A., 1990), and the University of California, Davis (Ph.D., 1994). Harkness also studied abroad at Oxford University. She is a well-regarded historian of science and medicine, as well as having studied alchemy, magic and the occult.
Harkness is a professor of history and teaches European history and the history of science at the University of Southern California. She has published two works of historical non-fiction, John Dee's Conversations with Angels: Cabala, Alchemy and the End of Nature (1999) and The Jewel House: Elizabethan London and the Scientific Revolution (2007).
In 2011, Harkness published her first work of fiction, A Discovery of Witches. The first novel in the All Souls trilogy, A Discovery of Witches is a historical fiction novel that tells the story of a modern-day witch who inadvertently calls up an ancient enchanted manuscript at Oxford University's Bodleian Library thereby attracting the unwelcome notice of a host of magical creatures who live among humans, including other witches, daemons, and a 1,500-year-old French vampire. The novel debuted at number two on The New York Times Best Seller hardcover fiction list, and has been sold in at least 34 countries. The book was called "a sophisticated fairy tale for adults" by the San Antonio Express-News. The second novel in the series, Shadow of Night, was published a year later, becoming a number one success on The New York Times Best Seller list. The third novel in the series is called The Book of Life. The book was published on July 15, 2014 in hardback, e-book, and audiobook in the US, UK, Canada, and Ireland.
On January 9, 2014, the United States front cover and a two-page excerpt were released to the public on USA Today. On May 12, 2014, chapter 1 was released on Harkness' website. Harkness is also the author of the award-winning wine blog, Good Wine Under $20.
Harkness released a companion book in May 2018 entitled The World of All Souls: The Complete Guide to A Discovery of Witches, Shadow of Night, and The Book of Life (All Souls Trilogy), and will be releasing a book in another series set in the same universe featuring secondary characters in The All Souls Trilogy — Time's Convert, to be published September 2018. The book stars Marcus Whitmore, Matthew Clairmont's vampire son.
Harkness is an executive producer of BadWolf's eight episode television series based on Harkness' novel, A Discovery of Witches, scheduled for release beginning in September, 2018. Further episodes are anticipated based on the sequels, Shadow of Night and The Book of Life.
