The world is split into the North and South. In the North, Sunchild Cordelia rules with a careless hand. Because Sunchild Cordelia refuses to leave the castle and spread light and energy, the North has long fallen to ruin—and with the decay of trees, clean air has become a commodity that only the wealthy can afford. Guardian of the Sun: The Weight of a Life follows siblings Nash and Nova, orphans that scam their way to survival. Nash’s cough is worsening though, and only clean air through a specialized mask can improve it—something they can’t yet afford. Nova would do anything for her brother and will carry him however far it takes, even if that means piggy-backing him to the Inner Circle to make more money. But the Inner Circle is different from their wide-spread Outer Circle life, and things will change forever because of their trip—especially when Nova accidentally kills someone for a mask. Now they’re on the run, and Nash is only getting worse.
