Maggi Andersen and her lawyer husband are empty nesters, living in the country-side outside Sydney, Australia with the cat that rules them. She began writing adventure stories at age eight. Three children, a Bachelor of Arts degree and a Master of Arts in Creative Writing degree later, her novels are still adventure stories, but are also passionate romances. Georgette Heyer among others, brought inspiration to her seductive Regencies and she also writes contemporary romantic suspense, darker, Victorian mysteries and young adult novels.

She supports the RSPCA (The Royal Society for the Prevention of Cruelty to animals) and animals often feature in her books.
