One morning, Deming Guo’s mother, Polly, an undocumented Chinese immigrant, goes to her job at a nail salon—and never comes home. No one can find any trace of her. With his mother gone, eleven-year-old Deming is left mystified and bereft. Eventually adopted by a pair of well-meaning white professors, Deming is moved from the Bronx to a small town upstate and renamed Daniel Wilkinson. But far from all he’s ever known, Daniel struggles to reconcile his adoptive parents’ desire that he assimilate with his memories of his mother and the community he left behind.
