The sequel to "The Glass Balls" (which you should read first) describes Dom's new career as lover-in-residence in Renaissance Florence, and narrator Olivia Wright's emergence as a sexually fulfilled woman.
The parallel adventures of Olivia Wright, art historian and sensuous woman, and Dom, the medieval youth, continue. Livy rediscovers a secret of Italian art and deflowers a young boy, while Dom experiments with gay love before finding two old friends.
In this continuation of the "Glass Balls" saga, Livy and her husband introduce a young virgin girl to sex, while in medieval Rome, Dom is hired to impregnate his host's wife while keeping two other women sexually satisfied.
In this story concluding the series, modern-day Livy enjoys the favors of three men and two women at once while, in medieval Italy, Dom impregnates two women and reunites with the woman who, years before, made a man of him. (There's more about the story in my blog.)
