After leaving the steno chair, Costa trained in Holistic Nutrition before graduating from the Toronto College of Homeopathic Medicine. She trained as a practitioner of Bowenwork and Reconnective Healing. She wrote holistic health blogs and contributed to health journals such as Bowen Hands and Wise Traditions before shifting to fiction writing where she often incorporates her knowledge into her stories.
At Sarah Selecky’s Writing School, Costa’s writing style was diagnosed as ‘Deeper Than You Think,’ a term coined by Selecky and defined as “deceptively straightforward and carefully crafted” and “more philosophical than you let on.”
Costa grew up on a farm in Perth County, southern Ontario, where she enjoyed the solitude of country living. She filled her hours reading books under the back yard maple tree while trying to ignore her pesky brothers. Attending her rural elementary school, she received solid instruction in grammar, punctuation, and sentence structure, some of which she still remembers.
She writes from London, Ontario, and is actively involved in the London Writers’ Society.
