Nineteen years ago, farmgirl Skye Herder was all chaste, a forbidden temptation, while her older sister was a ripe, willing female. A boy on the brink of manhood, Cash Benedict had to choose. Now, tormented by memories, compelled by desire, Cash was back. And Skye was a woman grown. Haunting, unforgiving, completely unforgettable, she embodied the beguiling past . . . and the electrifying future. For beside Skye stood a boy on the brink of manhood. A boy enough like Cash to be his son.
