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.

There, he will stop at nothing to bring down his enemies. Even if it means becoming one of them . . .
