Reading Murderbot Diaries by Martha Wells

I’ve been reading two books of the Murderbot Diaries by Martha Wells recently: All Systems Red and Artificial condition. They are about a SecUnit which job it is to protect humans. Humans usually treat those bots very bad, even if they are there for protection of humans, and most of the time, the bot is in its armour suit and looks like a robot. It still consists of lots of human biological tissue and without armour it might go unnoticed in a crowd of humans. This particular SecUnit was in a very bad accident, where some humans were killed apparently and suspects its governor modul to be broken, which is why it hacked it and is now free. It calls itself a murderbot because of that accident.
