AUDREY BLAKE has a split personality-- because she is the creative alter ego of Regina Sirois and Jaima Fixsen, two authors who met online in a survivor style writing contest. They live 1500 miles apart, but both are prairie girls: Jaima hails from Alberta, Canada, and Regina from the wheatfields of Kansas. Both are addicted to history, words, and stories of redoubtable women, and agree that their friendship, better and longer lasting than any other prize, is proof that good things happen in this random, crazy universe.
