Anna McCormac's heritage is Lakota Sioux and Irish. Raised in Santa Cruz, California, she immigrated to Sydney, Australia, where she practised herbal medicine, focused on antenatal and women's health. As a history enthusiast, Anna suspected that the Witch craze era held more than superstition, and began botanical and forensic investigations into the daily lives of people in the 17th century. She currently works as a registered Nurse, holding a Masters in Advanced Clinical Nursing, with a focus on vulnerable populations. Anna spends the rest of her hours working on her next books, and time with her husband and four grown children.
