The Murderbot Diaries is a science fiction series by American author Martha Wells, published by Tor Books. The series is about a cyborg-like construct designed as a Security Unit (SecUnit). The SecUnit manages to override its governor module, thus enabling it to develop independence, which it primarily uses to watch media. As it spends more time with a series of caring people, it starts developing friendships and emotional connections, which it finds inconvenient.
