In California's Silicon Valley, even a children's playgroup can be a place for power-brokering, innovation, and cut-throat competition.

In Oak Valley, a wealthy suburb of Silicon Valley, Alex Drake runs the playgroup in town. Even in a place where it seems like everyone has a multi-million dollar bank account or has a company that is about to go public, Alex appears to have it all: a delightful daughter, a handsome, adoring husband, model-like beauty, and the kind of obscene wealth that keeps her in the latest fashion, driving the newest car (electric, obviously!), and hosting playgroups where the wine flows—and so does the gossip.

When Alex invites new to the neighborhood Cleo Baird to join her tight-knit playgroup, Cleo can't believe her luck and knows she has just the "in" she's been hoping for.

But it isn't just luck. As the women grow closer and Alex shares more secrets, she doesn't realize Cleo is keeping secrets of her own. It's no coincidence that Cleo and her daughter moved to Oak Valley. Cleo came to town with a specific goal in mind: to destroy Alex's enviable and seemingly perfect life.

Fans of Tarryn Fisher, Jessica Knoll, and Frieda McFadden will love this book about friendships, betrayal, and how nothing, and no one, are ever exactly as they seem.
