Playing Nice

A couple's pleasant little life is upended by the revelation that their son was switched at birth in this gripping psychological thriller from the New York Times bestselling author of The Girl Before. Pete Riley stays at home; his partner, Maddie, is the breadwinner. He spends his days pacifying their rambunctious son Theo and browsing parenting blogs, where no concern is too trivial. Then, one day, a knock at the door. Miles and Lucy, a posh and near-perfect couple, tell Pete something shocking: Theo isn't his son. Their children were switched at the hospital. At first, the couples are determined to reach a mutual agreement. They're all nice, rational people; surely they can sort this out between them. But soon their precarious arrangement--of babysitting, play dates, and shared parenthood--begins to erode under the weight of perceived slights, hidden anxieties, and petty jealousies. It isn't long before Miles reveals himself to be cold, commanding, and aggressive. When he brings a custody case against the Rileys, their parenting abilities are suddenly under scrutiny and their private lives become ammunition. That's when their damaging secrets are exposed, their relationship tested to its breaking point. They might teach their son to share and behave, to say "please" and "thank you." But when it comes to protecting their family, Pete and Maddie are through with playing nice.
