In this twisty, hilarious novel, New York Times bestselling author Jen Lancaster explores what happens when a marriage, friendship, revenge, and the human capacity for deception collide.

Call to order the Friday Night Doom Crew.

They're an eclectic group of true-crime enthusiasts--a forensic psychologist, historian, and popular Instagram presence among them--dedicated to sleuthing out nefarious offenders and doing whatever it takes to set things right. But when dark secrets threaten one of their own, the Doom Crew grapples with how far they are willing to go to protect her.

Diana Pulaski is the crew's meticulously organized beating heart whose physician husband, Peter, is secretly a swindler behind an illegal pill mill, not to mention a loathsome cheater involved in an online romance. When they discover the truth, the amateur vigilantes have a plan to make Peter pay. Unfortunately, the closer Diana's friends are to hunting Peter down, the closer they get to discovering a secret Diana has been hiding.

As the fumbling Doom Crew's wild ride of vengeance goes awry, they must navigate the consequences of their actions. And Diana, forced to confront the past, must decide to whom she will remain loyal--no matter the cost.
