The Poe Clan is a family of vampiric immortals who feed on human life energy and live outside ordinary time. Siblings Edgar and Marybelle are initiated while still too young and become permanently fixed near adolescence, carrying centuries of memory through changing generations. Their existence—and that of other young immortals drawn into their orbit—touches many mortal lives, turning endless youth into a story about attachment, loss, and what it means to outlive the people one loves.
