Ruby Walsh has spent two years hiding behind merger agreements and corporate acquisitions, burying her grief in work since her wife's death. Her mansion in The Ridges, Las Vegas's most exclusive enclave, has become an empty shrine to a life no longer lived, but the night she confronts her neighbor about the music coming from her property, everything changes. Athena Stavros runs the Olympus, the Strip's most glamorous casino, but her true domain lies hidden beneath her home-a secret world of indulgence accessible only to a select circle of powerful women. Behind her white armor-tailored suits and wide-brimmed hats-stands a woman who orchestrates desire but never loses control... until she meets Ruby. In the shadows of Sin City two women accustomed to writing the rules become caught in a dangerous dance of their own making. When power shifts, the greatest risk might not be falling into desire, but daring to believe in something more.
