The Murderbot diaries by Martha Wells is just flat out fun. It is about a cybernetic robot who gains consciousness and just wants to be let alone to watch his “stories”. But the universe and its humans have other ideas. Murderbot is snarky and despite avoiding humans comes to care about a few of them.
I’ve just started reading the sixth in the series, Fugitive Telemetry. Each book in the series is a short quick read. They are a combination of mystery and thriller. I thoroughly enjoy them and highly recommend them to others.
