Struggling with a tormented past, undergraduate Olivia Winter once led a practical but isolated life. Then she met Professor Dean West, a brilliant scholar of medieval history who melted Liv's inhibitions and taught her the meaning of both love and erotic pleasure. But after three years of a blissful, lusty marriage, Liv and Dean now face a crisis that threatens everything they believe about each other...and sex might not be enough to save them.
