Network Effect, by Martha Wells

The first full Murderbot novel, following the four novellas, sees the rogue SecUnit working under contract to Preservation while it works out its future. It is sent on a survey trip to protect President Mensah’s adolescent daughter Amena. On the return home the expedition group is kidnapped, but to what end? SecUnit’s AI mentor ART is somehow involved, but for good or evil? This terribly complicated plot further develops the interstellar political situation of evil corporations and the resistance to them, as well as the personal development of Murderbot. For non-geeks it is easy to get lost in the science and coding, but there is action aplenty and it is a fascinating world.
