Ginna sold her first novel in 1983, after winning the Golden Heart Award, given by Romance Writers of America for the best unpublished novel in a category. She has been working as a full-time writer ever since. When she finishes her current contracts, Ginna will have written 33 books. She has also given many lectures and writing workshops, and judged in writing contests.

A native Texan, Ginna lived in Houston all her life — until 1993, when she and her husband Brad built their "dream home" and moved to the mountains of Colorado. Ginna also enjoys other creative activities such as oil painting, sewing, sketching, knitting, and needlepoint. "But my first love will always be writing. It is simply part of who I am."
