Government regulations said they had no choice. 15-year-old Philadelphia must stay on Earth in the hand of complete strangers while her father is sent against his will to Mars. When a Martian leader pulls the strings at the last minute and allows her to accompany her father, Philadelphia knows she must keep her head down or be sent back to Earth. But when a search for her deceased brother’s belongings leads her into a hallway that isn’t supposed to exist, Philadelphia is faced with a question she doesn’t want to answer – the choice between returning to Earth or destroying it.
