As a Red, Darrow grew up working the mines deep beneath the surface of Mars, enduring backbreaking labor while dreaming of the better future he was building for his descendants. The Society he faithfully served was built on lies. Betrayed and denied by their elitist masters, the Golds, the only path to liberation for Darrow's kind is revolution.

To honor the greater good for which Eo, his true love and inspiration, laid down her own life, Darrow sacrifices himself. He becomes a Gold, infiltrating their privileged realm to destroy it from within. As a lamb among wolves in a cruel world, Darrow finds friendship, respect, and even love—but also the wrath of powerful rivals. To wage and win the war that will change humankind's destiny, Darrow confronts treachery, overcomes his desire for retribution, and strives for a hopeful rebirth rather than violent revolt.

The road ahead is fraught with danger and deceit, but Darrow must follow Eo's principles of love and justice to free his people. He must live for more.
