The eldest son and heir to Castle Leger, Lance St. Leger is plagued by an infernal restlessness that cannot be appeased, perhaps because the family legacy of strange powers is most pronounced in Lance's own dubious lift. He calls it night drifting-his ability to spirit into the night while his body remains behind. And it is on one wild night that he finds Rosalind, a young, sheltered widow who mistakes Lance's "drifting" soul for the ghost of Sir Lancelot. Lance teases and tempts her, fills her with a yearning her chivalrous phantom knight cannot satisfy. But in this place imbued with both true love and otherworldly magic, a new dire portent vows to come full circle. As murderous enemy challenges the St. Leger power, Rosalind must tempt magic herself to save her beloved from the cold depths of eternal damnation.
