Marcia Preston (M.K. Preston) grew up on a wheat farm in central Oklahoma. From her father she learned the art of storytelling; from her mother, a reverence for books; and from Oklahoma’s red earth, a love of wildlife and the outdoors.

Her most recent novels are general fiction. The Butterfly House, under the byline Marcia Preston, hit number one on the HeatSeekers hit of debut fiction in the United Kingdom.  Others include The Piano Man about the emotional and psychological results of a heart transplant; Trudy's Promise, the story of a young mother's fight to regain her son when they are separated by the Berlin Wall; and The Wind Comes Sweeping, set on a wind farm and cattle ranch in Oklahoma.

Marcia earned degrees from University of Central Oklahoma, taught in public high schools for more than a decade, and worked for a time as PR and publications director for the National Cowboy and Western Heritage Museum in Oklahoma City. As a magazine writer for many years, she also edited and published ByLine, a trade magazine for aspiring writers. Marcia lives beside a creek in central Oklahoma, where she feeds the birds and dodges tornadoes.
