Libby always thought her life was well-ordered, charmed even: three gorgeous daughters, a husband who adores her, friends to see her through thick and thin. But lately, with one daughter in a constant fit of teenage sulks, a ten-year-old questioning everything in the universe and beyond, and a husband who seems to see her mainly as the manager of school runs, ironed shirts and a well-stocked fridge, motherhood is showing some of its distinctly uglier sides.
