Miller began to seriously pursue a writing career in her late forties after her sons were grown.
After joining Romance Writers of America in 2001, she began submitting full-length inspirational novels to various publishers.
Her interest in the post-civil war lumbering era in Michigan inspired a historical series beginning with The Measure of Katie Calloway (2010) followed by A Promise to Love (2011) and Under A Blackberry Moon (2013).
She is working with co-author Paul Stutzman on a non-fiction book entitled The Wisdom of Amish Parenting.
After several years working as a court reporter in Detroit, Michigan, she and her husband moved back to their hometown of Minford, Ohio where he is the minister of the Sunshine Church of Christ.
