Fergus' first novel, One Thousand White Women: The Journals of May Dodd was published by St. Martin's Press in 1998. The novel won the 1999 Fiction of the Year Award from the Mountains & Plains Booksellers Association, and has become a favorite selection of reading groups across the country. It has since sold over 250,000 copies in the United States. An international bestseller, One Thousand White Women (Milles Femmes Blanches) was also on the French bestseller list for fifty-seven weeks and has sold well over 400,000 copies in that country.

An historical fiction set in the 1930's in Chicago, Arizona, and the Sierra Madre of Mexico, The Wild Girl has also been embraced by reading groups all across the United States. Winston Groom, author of Forrest Gump called it, "an exhilarating and suspenseful tale that makes the heart soar."
