Enigma Nine — Ronnie G. Anderson

Enigma Nine (54,544 words) This is the third book in the Reptoid series. Mankind finds itself looking for a new home away from Earth. While Earth is now far too warm for humanity, Reptoids would find it delightful occupancy. That would never do to have such a threat within the solar system. Recently discovered other planets far out near the edge of the Kuiper Belt offer mankind hope as they travel to the nearest star to try to inhabit Proxima B. Currently mankind's home was living in city-ships - massive constructions not dependent upon land masses anywhere and the threat of Reptoids everywhere!
