After mother of five and former FBI profiler Andie Stern solved a murder--and unraveled a decades old conspiracy--in her New Jersey town, both her husband and the West Windsor police hoped that she would set aside crime-fighting and go back to carpools, changing diapers, and lunches with her group of mom-friends, who she secretly calls The Cellulitists. Even so, Andie can't help but get involved when the husband of Queen Bee Molly Goode is found dead. Though all signs point to natural causes, Andie begins to dig into the case and soon risks more than just the clique's wrath, because what she discovers might hit shockingly close to home.

Meanwhile, journalist Kenny Lee is enjoying a rehabilitated image after his success as Andie's sidekick. But when an anonymous phone call tips him off that Molly Goode killed her husband, he's soon drawn back into the thicket of suburban scandals, uncovering secrets, affairs, and a huge sum of money. Hellbent on justice and hoping not to kill each other in the process, Andie and Kenny dust off their suburban sleuthing caps once again.
