"A debut novel with a big supernatural canvas.… Its ambitions are world-sized, ranging across history and zeroing in on DNA, human and otherwordly. Age-old tensions between science and magic and between evolution and alchemy erupt as Diana seeks to unlock the secrets of Ashmole 782."
—Los Angeles Times
"Romantic, erudite, and suspenseful… Harkness attends to every scholarly and emotional detail with whimsy, sensuality, and humor."
—O, The Oprah Magazine
"A Discovery of Witches, a thoroughly grown-up novel packed with gorgeous historical detail, has a gutsy, brainy heroine to match: Diana Bishop, a renowned scholar of 17th-century chemistry and a descendant of accomplished witches.… Harkness writes with thrilling gusto about the magical world. Whether she's describing a yoga class for witches, daemons, and vampires or Diana's benignly haunted house, it's a treat to suspend disbelief.… As the mysteries started to unravel, the pages turned faster, almost as if on their own. By the most satisfying end, Harkness had made me a believer."
—Karen Valby, Entertainment Weekly
"Harkness conjures up a scintillating paranormal story.… Discover why everyone's talking about this magical book."
"A wonderfully imaginative grown-up fantasy with all the magic of Harry Potter or Twilight… An irresistible tale of wizardry, science and forbidden love, A Discovery of Witches will leave you longing for the sequel."
