Author Jennifer L. Holm asks the question, “how far would you go to save the people you love?” Besides spending his whole life on Mars, Bell is just like any other kid. He loves cats, eats all kinds of cake, and is curious about everything. Like, why do teenagers act so weird? And why did his best friend, Trey, suddenly want to switch rooms? But most of all, Bell wonders about the secrets the adults keep. Why doesn’t the US colony have contact with anyone in the other Mars settlements? Is it really so dangerous out there? And why are they always so alone?
When a virus breaks out and the grown-ups get sick, Bell and the other kids are oddly immune. And soon it’s up to Bell to find his courage, uncover the truth, and face the terrifying unknown to save his family.
