It starts as a game at a book group one night. Never Have I Ever... done something I shouldn't. But Amy Whey has done something she shouldn't. And Roux, the glamorous newcomer to Amy's suburban neighbourhood, knows exactly what that is. Roux promises she will go away – if Amy plays by her rules. But Amy isn't prepared to lose everything. She's going to fight back, and in this escalating game of cat and mouse, there can be only one winner.
