Eleven-year-old Waltraut wants to fit in at school, but it's not easy. Not only does her name rhyme with the ethnic slur that is often hurled her way, but no one can relate to her immigrant family and their complicated past. On weekends, however, she attends German school with friends who are just like her. They share a language, food, and customs-and they understand what it's like to live in two cultures.

As Waltraut navigates between her two worlds, she copes by reading and imagines how much easier her life would be if her name was Nancy, like the heroine of her favourite mystery series. So when her family moves to a new neighbourhood, Waltraut seizes the chance to reinvent herself. But she soon learns price of pretending to be someone else. With support from an insightful teacher, a warm-hearted father, a tough-minded mother, and even her annoying younger brother, she embraces her true self, with all of its complexities and contradictions.
