"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."
