Afternoons of a Woman of Leisure — Elizabeth Bennett

As a beautiful young woman married to a much older, wealthy man, Joanna has the life of a woman of leisure: a great deal of comfort, and little satisfaction. With her husband "going through a phase" of disinterest in her sexually, Joanne decides to embark on a phase of her own...

Venturing out in the afternoons, she discovers the mysterious O, a woman whose employees help clients explore the bounds of pleasure and pain. Her initial experiences are a shock to the senses...a shock that leaves her wanting more. But as she gets deeper into this exciting and dangerous world, Joanna finds herself the victim of shifting alliances, and begins gathering secrets to plot a revenge that goes further than anyone could have imagined.
