Stephanie Plum is back in action, this time on the trail of Maxine Nowicki, a thief and extortionist who seems to have vanished into thin air. Nabbing Maxine would solve Stephanie's financial problems, but there's a catch: Maxine's friends are mysteriously turning up dead.

To complicate matters, Stephanie's arch nemesis since grade school is also hunting for Maxine, hoping to cash in before Stephanie does. Meanwhile, her mentor and tormentor, Ranger, needs her help, and vice cop Joe Morelli has invited her to move in... temporarily.

Adding to the chaos, Stephanie's Grandma Mazur, her sidekick Lula, and a six-foot-tall transvestite rock musician want to take her to Atlantic City. One thing is for sure: no good can come from any of it.
