Stephanie Plum has a way of attracting danger, lunatics, oddballs, bad luck... and mystery men. And no one is more mysterious than the unmentionable Diesel. Hes back and hot on the trail of a little man in green pants whos lost a giant bag of money.
Problem is the money isnt exactly lost. Stephanies Grandma Mazur has found it, and like any good Jersey senior citizen shes high-tailed it in a Winnebago to Atlantic City and hit the slots.
With Lula and Connie in tow, Stephanie attempts to bring Grandma home. But the luck of the Irish is rubbing off on everyone. Lulas found a job modeling plus size lingerie, Connies found a guy, Diesels found Stephanie. And Stephanie has found herself in way over her head...
