The Murderbot Diaries by Martha Wells is a series where the audio book is better than reading. The murderbot is a sentient robot who no longer has a compliance chip, so he fakes it so he can stay free. He hires himself out for security jobs. The murderbot is dark, witty and ambivalent about human life. The narrator sounds like a young Samuel L. Jackson. The series is not long, many of the stories are novellas, but it is just hilarious in parts. Definitely worth listening to if you don’t mind some cursing.
