At Matthew's ancestral home, Sept-Tours, they reunite with the beloved 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.
