Perfect series for your reading list: “Red Rising,” written by Pierce Brown. The debut, “Red Rising,” introduces readers to the main character, Darrow, a member of the lowest-ranked caste in a color-coded society of the future. Darrow must sacrifice everything to infiltrate the Gold’s society and change the future of civilization.
In the second book, “Golden Son,” Darrow climbs the ranks of the elite, and in the third book, “Morning Star,” he gathers other societies to defeat them.
I’m on the fourth book, “Iron Gold,” then it’s onto the fifth and final one, “Dark Age.” I highly recommend.
