Big Little Lies by Liane Moriarty

A murder...A tragic accident...Or just parents behaving badly? What’s indisputable is that someone is dead.  Madeline is a force to be reckoned with. She’s funny, biting, and passionate; she remembers everything and forgives no one. Celeste is the kind of beautiful woman who makes the world stop and stare but she is paying a price for the illusion of perfection. New to town, single mom Jane is so young that another mother mistakes her for a nanny. She comes with a mysterious past and a sadness beyond her years. These three women are at different crossroads, but they will all wind up in the same shocking place.  Big Little Lies is a brilliant take on ex-husbands and second wives, mothers and daughters, schoolyard scandal, and the little lies that can turn lethal.
