Carlotta Wren is off on another adventure--this time following a lead from her jailbird father to Las Vegas to find out what happened to her long-lost mother. Unaware of Carlotta's mission, her brother Wesley tags along with grandiose designs of winning big with a secret bag of cash he found. But as soon as the Wren siblings hit Sin City, their luck runs cold. A dead man spoils Carlotta's plan and before she knows it, the entire gang from Atlanta has descended to aid, abet, and aggravate. Wes has problems of his own when it turns out the found money belongs to seriously bad men who want it back. With the odds stacked against them, Carlotta and Wes keep rolling the dice. Too late, Wes learns he's accidentally blown his father's case wide open. Someone wants the Wrens--all of them--to cash in their chips for good. And when Carlotta uncovers the real reason behind her parents' disappearance, it yanks her life in a new direction.
