Something's in the air... but it's not oxygen. There is no sun. The environment is toxic. Every survivor is an empty soul willing to kill for one more breath of clean air. There are no morals, no laws, no last names. Nitra is the only one left in her family. She struggles each day to find a reason to not step out onto the frozen surface of the earth to numb her pain forever. Thane is a natural protector. So when he found teenage Nitra alone, running toward the enormous ice wave that would render humanity nearly extinct, he vowed to move heaven and earth to save her. Thane and Nitra must ensure their own survival and protect the life of Thane's younger brother. But there is only one way to succeed, and it means rejecting everything they've ever known.
