The Ganymedan R.T. Ester

Verden Dotnet made an easy living mixing drinks for the creator of all sentient tech in the galaxy—until he decided to kill the creator. Now this man is dead, really dead, no cloud back-ups, and V-Dot is on the run, carrying a galaxy-shattering secret in his pocket. When he misses the last ship back to Ganymede, he convinces an old, outdated but still sentient ship, TR-8901, to give him a lift.

But TR suspects that something is up—it is hearing rumours about his creator’s death, and the man who fled the scene. But TR is a dutiful ship, and will carry out its duties until proven otherwise…
