Artificial Condition by Martha Wells
My rating: 5 of 5 stars
Rounding up from 4.5 because this doesn't stand alone - if you haven't read All Systems Red (a 2018 Alex Award Top Ten), this won't make as much sense.
Murderbot has decided to go rogue and figure out what really happened during the gap in its memory. He - it's decided it's a 'he' - travels back to the scene of the supposed crime, thinking he can go it alone. Of course, he can't and it's only with ART's help that he not only manages the trip but also finds employment. Answers? Well... some. It's clear that we'll have to wait until the third book for more about what happened, who ordered it and how Murderbot will respond.
I'm loving this series and the challenges to our concepts of what is, and is not, artificial life. The idea that a Security Unit would just really want to bingewatch soaps is funny. ART's reaction to those soaps? Equally funny.
