Book excerpt: Kitty loves living at the isolated Hay House with her doting grandparents, but it cannot provide the adventure and excitement that her restless, bohemian mother Marina craves. When a guru sees Marina's future in New York, Kitty is torn from her home and bounced from place to place—first a colorless boarding school, then an American ashram, and finally back to an unfamiliar England. But soon, no god, man, or martini can staunch Marina's hunger for a happiness that proves all too elusive. And Kitty, turning fifteen, must choose: whether to play dangerous games with the grown-ups or put herself first. With this witty and poignant debut novel, Sophie Dahl ably carries on the literary legacy of her grandfather, the beloved children's book author Roald Dahl.
