Originally published in a slightly different form by Dial Books for Young Readers in 2015.

Ten-year-old Ada has never left her family's one-room apartment. Her bitter mother is too humiliated by Ada's twisted foot to let her outside. But when her little brother, Jamie is going to be shipped out of London to escape World War II, Ada doesn't waste a minute: she sneaks out to join him. So begins a new adventure for Ada, and for Susan Smith, the woman who is forced to take in two kids. As Ada teaches herself to ride a pony, learns to read, and watches for German spies, she begins to trust Susan - and Susan begins to love Ada and Jamie. But in the end, will their bond be enough to hold them together through wartime? Or will Ada and her brother fall back into the cruel hands of their mother?
