Red Rising 2. Golden Son (Red Rising Trilogy)

For seven hundred years, my people have been enslaved without voice, without hope. Now I am their sword. And I do not forgive. I do not forget. So let them think they own me. Let them welcome me into their house, so I might burn it down.
Hic sunt leones.
Darrow is a rebel forged by tragedy. For years he and his fellow Reds worked the mines, toiling to make the surface of Mars inhabitable. They were, they believed, mankind's last hope. Until Darrow discovered that it was all a lie, and that the Red were nothing more than unwitting slaves to an elitist ruling class, the Golds, who had been living on Mars in luxury for generations.
Now fully embedded amongst the Gold ruling class, Darrow continues his dangerous work to bring them down from within. It's a journey that will take him further than he's ever been before - but is Darrow truly willing to pay the price that rebellion demands?
