Ruth Langan contributed to twelve multi-author anthologies over three decades. Early entries were romance-focused (Harlequin Historical Christmas Stories, Once Upon a Castle, Once Upon A Star), while later anthologies leaned paranormal (Moon Shadows, Bump in the Night, The Lost, Suite 606, The Other Side, The Unquiet, Mirror, Mirror, Down the Rabbit Hole). The shift mirrors Langan’s own move toward paranormal themes in her later career.
