Katherine Fairfield is a forty-four-year-old green witch who walked away from Hex Support—the Federal Bureau of Magic's secret investigative division—after her husband's death. Now her children are in college, her younger sisters are grown, and she spends her days managing the enchanted Fairfield estate, Dark Hollow. When her former boss arrives with an irresistible case, Kit reluctantly dusts off her badge and re-enters the world she once abandoned.

Katherine 'Kit' Fairfield is a capable, experienced witch who leads with competence rather than stumbling through magical discovery. Elizabeth is the book witch, scholarly and measured. Grace is the family rebel—creative, fun-loving, and irreverent. Together they form a complementary trio united by loyalty and their shared magical heritage.

Across three books, each of the three Fairfield sisters takes center stage in her own investigation, gradually pulling all of them back into the supernatural world. The series balances cozy mystery plotting with light romance and family dynamics, culminating in each sister proving herself worthy of the Fairfield name while forging new connections—both professional and personal.
