It's unbelievable how much the three female characters in Montana Sky ressemble the three heroines in Roberts' Three Sisters Island trilogy. There's Willa, the tough cowgirl, who reminds me of Ripley, of Heaven and Earth. Then there's Tess, feminine and sophisticated, sure of her own sexuality, just like Mia in Face the Fire. Finally, there's Lilli, a battered wife, scared of her own shadow, who takes refuge in the ranch ("island" in the trilogy), the perfect clone of Nell from Dance Upon the Air.
