Red Rising by Pierce Brown
Book Description
Darrow is a Red, a member of the lowest caste in the colour-coded society of the future. Like his fellow Reds, he works all day, believing that he and his people are making the surface of Mars livable for future generations. But Darrow and his kind have been betrayed. Soon he discovers that humanity already reached the surface generations ago and Reds like him are nothing more than slaves to a decadent ruling class. Darrow sacrifices everything to infiltrate the next generation of humanityβs overlords' struggle for power.
