A silver cuff lies on the table at Learmonth Castle. It once held a werewolf who died at the Night Vigil’s hands, and every delegate in the room knows someone whose loss could be laid beside it. Thomas Learmonth has called the leaders of vampire houses, witch covens, and wolf packs together. They must agree how to share evidence, answer accusations, and act without turning on one another. Then a seer announces that Thomas will die, and the danger they hoped to face together arrives at his own door. As Charlotte, Rane, Fenna, and the rest of the family are drawn deeper into the fight, Thomas must hold a difficult alliance together long enough to find where the Vigil is going next.
