Twelve-year-old Bird Gardner lives a quiet existence with his loving but broken father, a former linguist who now shelves books in a university library. Bird knows to not ask too many questions, stand out too much, or stray too far. For a decade, their lives have been governed by laws written to preserve “American culture” in the wake of years of economic instability and violence. To keep the peace and restore prosperity, the authorities are now allowed to relocate children of dissidents, especially those of Asian origin, and libraries have been forced to remove books seen as unpatriotic—including the work of Bird’s mother, Margaret, a Chinese American poet who left the family when he was nine years old.
