"Every successful marriage has its own private language." So it is for baby-boomer Kate and her architect husband, Jack, decades into their comfortable metropolitan life together, and for millennial television writer Phoebe and her charming loafer of a partner, Tony. But everything changes when a steamy Netflix show called Cheating becomes the much-talked-about megahit of the moment--and somehow seems to include intimate details of their marriage that only Kate and Jack could ever have known. Who has cheated whom? Who has stolen whose story--and why? A black comedy of love, trust, entitlement, and revenge, Look What You Made Me Do is a suspenseful story of two very different women and two very different generations, and a battle only one of them can win.
