All Systems Red

Short. Fun. Brilliant.
First Nana (from The Travelling Cat Chronicles), and now Murderbot, I love these characters who are a mood in themselves. Murderbot, for one, is witty, caring, and uncaring in its own way.
The narration is centered towards character building, and it's through them one envisions this sci-fi world. You won't find vocabulary-heavy paragraphs describing the terrain, atmosphere, etc. Instead, you get byte-size information when necessary for the plot. The sci-fi context remains in the background, while the reader builds connections with the characters.
