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.

Scientist Beth Darlow has discovered the unimaginable. She's built a machine that allows human consciousness to travel through time—to any point in the traveler's lifetime—and relive moments of their life. An impossible breakthrough, but it's not perfect: the traveler has no way to interact with the past. They can only observe. After Beth's husband, the co-creator of the machine, dies in a tragic car accident, Beth is left to raise daughter—and continue the work they started. Mired in grief and threatened by her CEO, Beth pushes herself to the limit to prove the value of her technology.

What will become of our self-destructed planet? The answer shatters all expectations in this subversive speculation from the Hugo Award - winning author of the Broken Earth trilogy. An explorer returns to gather information from a climate-ravaged Earth that his ancestors, and others among the planet’s finest, fled centuries ago. The mission comes with a warning: A graveyard world awaits him. But so do those left behind - hopeless and unbeautiful wastes of humanity who should have died out ages ago.

Our universe is ruled by physics, and faster-than-light travel is not possible - until the discovery of The Flow, an extradimensional field we can access at certain points in space-time that transports us to other worlds, around other stars. Humanity flows away from Earth, into space, and in time forgets our home world and creates a new empire, the Interdependency, whose ethos requires that no one human outpost can survive without the others. It's a hedge against interstellar war - and a system of control for the rulers of the empire.

On his way to his betrothal, young Lord Penric comes upon a riding accident with an elderly lady on the ground, her maidservant and guardsmen distraught.
