A sexually frustrated 30-something is bored out of her gourd at Medieval Worlds: Dinner and Tournament when she heads for the ladies' room. She soon encounters a gorgeous mystery knight in a bathroom stall that is actually a portal to another time and place—a castle in 12th-century Europe, which is the knight's home.

Louise is ecstatic—she believes she has found the incredible knight-in-shining-armor of her wildest fantasies. But the mystery knight is actually Lord Verdigris, who has kidnapped her so she can become a sex slave in his Hall of Harlots, where she will grant sexual favors to Lord Verdigris and the knights of his garrison for all eternity!

Determined to make the best of a bad situation, Louise settles into her new role as Lady Louisa of the Crossroads—by far the most popular and desirable of all the courtesans in Lord Verdigris's Hall of Harlots.
