Exit Strategy

I enjoy these books. I actually have fun reading them, I just wish I remember them more when I'm done. Or maybe it's that I didn't read them back to back. I think I may have skipped one. I am really looking forward to the full length novel coming out.
That said, as a reminder to me: this one is number 4 in the series and Murderbot (should we start calling it Targetbot-as everyone and their brother wants it dead?) could take a vacation but it finds out Dr. Mensah is being held hostage by the evil GrayCris corp. Of course Murderbot does not have to help the humans, it just does. Also, Murderbot goes shopping and does not hate it.
