Elsie McPhee and her brother, Tommy, are hiding a terrible secret. They've been kidnapped -- not by a stranger, but by their mother. It is lonely and scary always hiding, moving, and not being allowed to make friends or to talk to people. Elsie even remembers the kidnapping, but she's so scared of her mother, she can't say or do anything.
Then Tommy gets sick, and Elsie needs to get help -- fast. But that means she has to leave the apartment. What if she gets caught? Does Elsie have the courage to help her brother even if it means breaking her mother's rules?
