All Systems Red

Having killed a handful of company employees on his previous job the self-described Murderbot quietly hacks it's own governor module and essentially becomes a petulant, self-conscious emo teenager that would rather watch soap operas than deal with humans. One armed with military grade weapons and defensive systems mind you.

Now on a planetary mission where things aren't adding up, the crew including Murderbot find themselves in mortal danger. Murderbot having gifted him/herself with free will is no longer restricted to following orders but still works to keep his/her human crew safe. The book doesn't overstay its welcome and manages to pack a tight little story in under 200 pages. And it looks like its building a world that will continue on with a new book slated for this year. A quick sci-fi hit.
