Book excerpt: Seventeen-year-old Samar -- a.k.a. Sam -- has never known much about her Indian heritage. Her mom has deliberately kept Sam away from her old-fashioned family. It's never bothered Sam, who is busy with school, friends, and a really cute but demanding boyfriend. But things change after 9/11. A guy in a turban shows up at Sam's house, and he turns out to be her uncle. He wants to reconcile the family and teach Sam about her Sikh heritage. Sam isn't sure what to do, until a girl at school calls her a coconut -- brown on the outside, white on the inside. That decides it: Why shouldn't Sam get to know her family? What is her mom so afraid of? Then some boys attack her uncle, shouting, "Go back home, Osama!" and Sam realizes she could be in danger -- and also discovers how dangerous ignorance can be. Sam will need all her smarts and savvy to try to bridge two worlds and make them both her own.
