Tails and Fixers By Charles Kaluza
Summary: Floyd was slowly dying and was given the chance to live; if he would agree to be an emissary from Earth. He is sent on a one way mission to a distant world in return for the promise of restored health from a secret stem cell treatment. He and his computer partner arrive fifty Earth years later only to find a planet which had been decimated by a major asteroid strike. The only survivors live in the Sanctuary deep below a mountain. The ruling council finds the idea of democracy a threat to the stability of the Sanctuary. Floyd is evicted from the Sanctuary to an expected death from the elements. Lina with her long fluffy tail, and Tesla a fixer, were to be eliminated in order to sanitize the thinking within the Sanctuary. With the help of the other fixers they escape and join Floyd in his struggle for survival.
