Darrow is a Helldiver. A pioneer of Mars.

Born to slave beneath the earth so that one day, future generations might live above it.

He is a Red - humankind''s lowest caste. But he has something the Golds - the ruthless ruling class - will never understand.

He has a wife he worships, a family who give him strength. He has love.

And when they take that from him, all that remains is revenge . . .
