Darrow is a Red, a member of the lowest caste in the color-coded society of the future. Like his fellow Reds, he works all day, believing that he and his people are making the surface of Mars livable for future generations. Yet he toils willingly, trusting that his blood and sweat will one day result in a better world for his children. But Darrow and his kind have been betrayed. Soon he discovers that humanity reached the surface generations ago. Vast cities and lush wilds spread across the planet. Darrow—and Reds like him—are nothing more than slaves to a decadent ruling class.

All Systems Red is the tense first science fiction adventure novella in Martha Wells' series The Murderbot Diaries. For fans of Westworld, Ex Machina, Ann Leckie's Imperial Raadch series, or Iain M. Banks' Culture novels. The main character is a deadly security droid that has bucked its restrictive programming and is balanced between contemplative self-discovery and an idle instinct to kill all humans.

A man. His ex-girlfriend's cat. A sadistic game show unlike anything in the universe: a dungeon crawl where survival depends on killing your prey in the most entertaining way possible. In a flash, every human-erected construction on Earth - from Buckingham Palace to the tiniest of sheds - collapses in a heap, sinking into the ground. The buildings and all the people inside have all been atomized and transformed into the dungeon: an 18-level labyrinth filled with traps, monsters, and loot.

Ryland Grace is the sole survivor on a desperate, last-chance mission - and if he fails, humanity and the Earth itself will perish. Except that right now, he doesn't know that. He can't even remember his own name, let alone the nature of his assignment or how to complete it. All he knows is that he's been asleep for a very, very long time. And he's just been awakened to find himself millions of miles from home, with nothing but two corpses for company.

The Catenan Republic—the Hierarchy—may rule the world now, but they do not know everything. I tell them my name is Vis Telimus. I tell them I was orphaned after a tragic accident three years ago, and that good fortune alone has led to my acceptance into their most prestigious school. I tell them that once I graduate, I will gladly join the rest of civilized society in allowing my strength, my drive, and my focus—what they call Will—to be leeched away and added to the power of those above me, as millions already do. As all must eventually do.
