Darrow is a sixteen-year-old Red Helldiver from Lykos, Mars. At the bottom of the social class, Darrow believes that his toil under the surface of Mars is to benefit all of humanity-- to make Mars' surface inhabitable for others like him. But after his wife is hanged for treason, Darrow learns that all of this was a lie--that on the surface, there are large cities and all ranges of Colors. Motivated by his wife's dream, Darrow is transformed into a Gold and sent to destroy the Color system that keeps Reds enslaved.
I really enjoyed this novel because it is set in a dystopian future where the other planets have been colonized. The sci-fi aspect of it is very cool, and it makes me excited to think about making Mars and other planets inhabitable. Darrow's transformation is sad because he's fueled by revenge, but reading him become more forgiving and see the good in Golds while also recognizing the bad in Reds makes his story more emotional. He defeats the odds on both sides, and he rises above his vengeance and realizes that his goal is not to destroy the Golds and make Reds powerful but to reform the Society. Its theme is parallel to society today, shedding light on marginalized communities fighting for equality.
