Book excerpt: The sparkling debut novel of Maria Semple, author of the WOMEN'S PRIZE FOR FICTION-shortlisted WHERE'D YOU GO, BERNADETTE, including reading group notes. Violet Parry is living the quintessential life of luxury in the Hollywood Hills with David, her rock-and-roll manager husband, and her darling toddler, Dot. She has the perfect life - but she's deeply unhappy. David expects the world of Violet but gives little of himself in return. When she meets Teddy, a roguish small-time bass player, Violet comes alive, and soon she's risking everything for the chance to find herself again. Also in the picture are David's hilariously high-strung sister, Sally, on the prowl for a successful husband, and Jeremy, the sportscaster savant who falls into her trap.
