Sure! So this book is Book 6 in the Red Rising series, so I’ll give a brief outline about the series in general.

It’s set in a distant future where humanity has colonized and terraformed the solar system, and in so doing divided themselves into a color-based caste system. The hero is Darrow, a Red, the lowest rung on the totem pole. After experiencing unspeakable loss at the hands of the elite Gold class, Darrow undergoes intensive gene therapy to physically impersonate a Gold and infiltrate their hierarchy, with the aim of toppling the caste system from within.

As allies turn into enemies and vice versa, Darrow must navigate the brutal, power-hungry culture of the Golds and make impossible choices to try and make a better future for the entire solar system.

The series starts off very YA in tone, but quickly progresses into a military/political thriller series.
