Red Rising

The Red Rising series follows Darrow, a member of the lowest caste (Reds) in a color-coded society, who discovers the higher castes have been lying about the terraforming of Mars. To get revenge, he undergoes a brutal transformation to become a Gold and infiltrates the elite's training academy to destroy the system from within. The story begins as a dystopian revenge tale but evolves into a vast, space-opera-style saga of war, politics, and rebellion across the solar system.
