Short sci-fi adventure books about a security bot that has hacked its governor modules and is now free. While not great literature, they are fast literature, and it's easy to read (and difficult not to read) each of these books in a single sitting. The main character is acerbic, the fights and situations are fast paced, the supporting characters are sympathetic, and the ShadowRun type corps and their plots make decent villains. The stories are consistently well done and fast paced and you like the characters and enjoy the time. I could list a few flaws (sci-fi hacking isn't the greatest mechanic given how much of the story it occupies), but overall these are quality entertainment.
