It began with A DISCOVERY OF WITCHES. Historian Diana Bishop, descended from a line of powerful witches, and long-lived vampire Matthew Clairmont have broken the laws dividing creatures. When Diana discovered a significant alchemical manuscript in the Bodleian Library, she sparked a struggle in which she became bound to Matthew. Now the fragile coexistence of witches, daemons, vampires and humans is dangerously threatened. Seeking safety, Diana and Matthew travel back in time to London, 1590. But they soon realise that the past may not provide a haven. Reclaiming his former identity as poet and spy for Queen Elizabeth, the vampire falls back in with a group of radicals known as the School of Night. Many are unruly daemons, the creative minds of the age, including playwright Christopher Marlowe and mathematician Thomas Harriot. Together Matthew and Diana scour Tudor London for the elusive manuscript Ashmole 782, and search for the witch who will teach Diana how to control her remarkable powers... Fall under the spell of Diana and Matthew once more in this stunning, richly imagined, epic tale.

"Together we lifted our feet and stepped into the unknown"—the thrilling sequel to the New York Times bestseller A Discovery of Witches

Deborah Harkness exploded onto the literary scene with her debut novel, A Discovery of Witches, Book One of the magical All Souls Trilogy and an international publishing phenomenon. The novel introduced Diana Bishop, Oxford scholar and reluctant witch, and the handsome geneticist and vampire Matthew Clairmont; together they found themselves at the center of a supernatural battle over an enchanted manuscript known as Ashmole 782.

Now, picking up from A Discovery of Witches’ cliffhanger ending, Shadow of Night plunges Diana and Matthew into Elizabethan London, a world of spies, subterfuge, and a coterie of Matthew’s old friends, the mysterious School of Night that includes Christopher Marlowe and Walter Raleigh. Here, Diana must locate a witch to tutor her in magic, Matthew is forced to confront a past he thought he had put to rest, and the mystery of Ashmole 782 deepens.

Deborah Harkness has crafted a gripping journey through a world of alchemy, time travel, and magical discoveries, delivering one of the most hotly anticipated novels of the season.
