Darrow is a Red, a member of humanity's lowest caste, toiling beneath the surface of Mars to make the planet liveable for future generations. Believing that his sweat and blood will create a better world for his children.
But everything Darrow has been told is a lie. Humanity reached the surface long ago. Vast cities and lush wilds spread across the planet, while Reds like Darrow suffer in the dirt.
Driven by revenge - and the memory of lost love - Darrow will sacrifice everything to infiltrate the legendary Institute, where the next generation of humanity's overlords struggle for power.
