"Iris Prince is starting over. After years of drifting apart, she and her husband are going through a surprisingly drama-free divorce. She's moved to a new house in a new neighborhood, and has plans for gardening, coffee clubs, and spending more time with her nine-year-old daughter Melanie. It feels like her life is finally exactly what she wants it to be. Then, one beautiful morning, she looks outside her kitchen window—and sees that a wall has appeared in her front yard overnight. Where did it come from? What does it mean? And why does it seem to keep growing? Meanwhile, a Silicon Valley startup has launched a high-tech wrist wearable called "the Band." Pitched as a convenient, eco-friendly tool to help track local utilities and replace driver's licenses and IDs, the Band is available only to those who can prove parental citizenship. Suddenly, Iris, a proud second-generation Mexican-American, is now of "unverifiable origin," unable to prove who she is, or where she, and her undocumented loved ones, belong. Amid a climate of fear and hate-fueled violence, Iris must confront how far she'll go to protect what matters to her most." -- Publisher.
