Luna Bell, a five-year-old orphaned medium, is cast out by her stepmother as a bringer of misfortune—yet with her gifts of purifying evil spirits and foreseeing danger, she saves Cain, heir of the Thorne conglomerate, and is adopted by the family's patriarch, Lyon, as his daughter. Within the wealthy household, she resolves crisis after crisis, reunites with her biological grandfather Ruby, and uncovers the scheme hatched by her stepmother Amy and executive Gavin. In the end, her spiritual power brings the resurrection herb into bloom, awakening her adoptive father. Her name cleared of disgrace, she at last gains true family love and a home to belong to.
