J. K. Rowling, Stephenie Meyer, Anne Rice—only a few writers capture the imagination the way that Deborah Harkness has with her New York Times–bestselling All Souls trilogy. A Discovery of Witches introduces reluctant witch Diana Bishop, vampire geneticist Matthew Clairmont, and the battle for a lost, enchanted manuscript known as Ashmole 782.

Picking up from A Discovery of Witches’ cliffhanger ending, Shadow of Night takes Diana and Matthew on a trip through time to Elizabethan London, where they are plunged into a world of spies, magic, and a coterie of Matthew’s old friends, the School of Night. As the search forAshmole 782 deepens and Diana seeks out 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.
