Void Moon

She had served five years in prison for conspiring with her previous partner-in-crime, Max Freeling, to steal the winnings of casino visitors while they were asleep.

When Cassie learns that Jodie will soon be moving to Paris with her adopted parents, she decides to return to theft in order to secure the funds needed to run away with her.

Leo is confident of Cassie's abilities despite her long hiatus but warns her to avoid being in hotel room of her target, a high roller, during the period of the "void moon" on the day of action.

It is revealed that high roller was actually a courier for Cuban gangsters in Miami, and that he had been carrying $2.5 million in the suitcase as partial payoff for rights to buy the Cleo.

The casino's chief of security, Vincent Grimaldi, hires private investigator Jack Karch–the undercover agent involved in the heist that ended in Max's death–to recover the money.

Cassie Black makes a cameo appearance (using her new name) in The Narrows (2004) and is referenced by attorney Mickey Haller as a former client in The Brass Verdict (2008).
