After traveling through time in Shadow of Night, the second book in Deborah Harkness’s enchant­ing series, historian and witch Diana Bishop and vampire scientist Matthew Clairmont return to the present to face new crises and old enemies. At Matthew’s ancestral home at Sept-Tours, they re­unite with the cast of characters from A Discovery of Witches—with one significant exception. But the real threat to their future has yet to be revealed, and when it is, the search for Ashmole 782 and its miss­ing pages takes on even more urgency. In the tril­ogy’s final volume, Harkness deepens her themes of power and passion, family and caring, past deeds and their present consequences. In ancestral homes and university laboratories, using ancient knowl­edge and modern science, from the hills of the Auvergne to the palaces of Venice and beyond, the couple at last learn what the witches discovered so many centuries ago.
