Eight hundred years of secrets are about to catch up with Thomas Learmonth. The Queen of Elfland has crossed into the mortal world, bringing with her an ancient power that even the oldest vampires have reason to fear. For Thomas, her return reopens a chapter of his life he has spent centuries concealing. His seven years in Elfland, the circumstances of his escape, and the mysterious binding have become essential to understanding a threat that extends far beyond his family. As Charlotte and Rane help him uncover the truth, a dangerous alliance between the Queen and the Vigil begins to reveal its purpose. Ancient magic, hidden thresholds, and a history deliberately erased from the record all point toward a confrontation neither world may survive unchanged. But the Queen's interest in Thomas is deeply personal, and those closest to him may become the means through which she finally settles an old debt. Caught between a centuries-old promise and an enemy determined to reclaim her power, Thomas must face the consequences of the one escape that changed his life forever. The first binding was made centuries ago. Its reckoning has only begun.
