Description: Cassie Black is a beautiful woman selling luxury cars in Los Angeles but she has many secrets.  One is that she recently finished serving six years in prison for manslaughter.   Another is the identity of the child she watches from afar when she is not working.   Cassie was planning to go straight but when she needs a large sum of money she ignores the warnings from her well-intentioned parole officer and approaches her old friend Leo for a gig.  Unfortunately, the only heist he has available involves returning to the Cleopatra casino in Las Vegas, where everything went so fatally wrong for her before.  What really happened that night is another secret.  Cassie’s instinct is to say no but she needs the money urgently, although Leo’s warning about the Void Moon both exasperates and unnerves her . . .
