J. K. Rowling, Stephenie Meyer, Anne Rice—only a few writers capture the imagination the way that Deborah Harkness has done with books one and two of her New York Times–bestselling All Souls trilogy. A Discovery of Witches introduced reluctant witch Diana Bishop, vampire geneticist Matthew Clairmont, and the battle for a lost, enchanted manuscript known as Ashmole 782. Hakness’s much-anticipated sequel, Shadow of Night, picks up from A Discovery of Witches’ cliffhanger ending. Diana and Matthew time-travel to Elizabethan London and are plunged into a world of spies, magic, and a coterie of Matthew’s old friends, the School of Night. As the search for Ashmole 782 deepens and Diana searches for a witch to tutor her in magic, the net of Matthew’s past tightens around them, and they embark on a very different—and vastly more dangerous—journey.
