After traveling through time in Shadow of Night, 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, Sept-Tours, they reunite with family and friends from A Discovery of Witches — with one significant exception. However, 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.
