All Systems Red (The Murderbot Diaries 1) by Martha Wells

“A damaged android on an exploratory mission takes center stage in this entertaining SF novella, the first book in the Murderbot Diaries series.

There’s some tense action, and a few of the scientists turn out to be more interesting and less helpless than they initially appear, but it’s the character of Murderbot that really makes the story come alive, a mix of flat robot personality with some surprising quirks, serious combat skills, a talent for coming up with effective plans – and a deep need to discover who it really is.” — Locus
