For five years, Jake Johns made a living playing the stock market. He then started to dabble in craps at a Las Vegas casino, because he found comfort in mathematics and a sureness in numbers- elements which were missing in his 12-year marriage. During one of his gaming sessions at Drake's Diamond Casino, he encounters Holly Simmons, who makes big bets and has a unique and reckless way of throwing the dice. Attracted to the "heretic shooter," first by her play and then by the obtuseness of her personality, he manages to forge a friendship which makes him reevaluate his marriage and his life's goals. Will he come out richer or poorer, smarter or foolish, from his new dalliance with gambling and a mystery woman? Holly soon becomes a Las Vegas celebrity because of her shooting style and the enormous success she enjoys at the craps table. She shoots with her eyes closed, and is often seen talking to herself before throwing the dice. People are convinced that there is an outside force that is guiding her hand. Who is Holly, the reclusive resident at the casino's hotel, and what is the story of her life? Craps aficionados will enjoy this story as much as romantics, who believe in the eternal and otherworldly aspects of true love.
