A "propulsive thriller about secret organizations, hidden agendas, and the lengths one woman will go to reclaim her life" (Laura Dave, author of Reese's Book Club Pick The Last Thing He Told Me) from USA TODAY bestselling author Catherine McKenzie. At thirty-nine, Nicole Mueller's life is on the rocks in "this brilliant, tangled web of lies, cover ups and deception" (Mary Kubica, New York Times bestselling author). Her once brilliant law career is falling apart. She and her husband, Dan, are about to be forced out of the apartment they love. After a warning from her firm's senior partners, she receives an invitation from an exclusive women's networking group, Panthera Leo. Membership is anonymous, but every member is a successful professional. It sounds like the perfect solution to help Nicole revive her career. So, despite Dan's jokes that the group might be a cult, Nicole signs up for their retreat in Colorado. Once there, she meets the other women who will make up her Pride. A CEO, an actress, a finance whiz, a congresswoman: Nicole can't believe her luck. The founders of Panthera Leo are equally impressive. They explain the group's core philosophy: they're a girl's club in a boy's club world. Nicole is all in. And when she gets home, she soon sees dividends. Her new network quickly provides her with clients that help her relaunch her career, and a great new apartment too. The favors she must provide in return seem benign. But then she's called to the congresswoman's apartment late at night where she's pressed into helping her cover up a crime. And suddenly, Dan's concerns that something more sinister is at play seem all too relevant. Is Panthera Leo full of predators? And is Nicole the prey?
