First Landing — Alastair Mayer

Franklin Drake's six-ship expedition to Alpha Centauri is down to five ships. His injured lead exobiologist has been replaced by the backup . . . who is his second-in-command's ex. And they haven't even left the Solar system.

The real headaches start when they reach their destination and lose another ship. Pushing on, they discover that their two target planets are far more Earth-like than they have any right to be. Almost as if they had been deliberately terraformed . . . . millions of years ago. If they survive the hazards of the planet, what they find will lead Drake to a decision that could get him court-martialled when -- or if -- they return.

First book in the completed Alpha Centauri trilogy, the prequel to the T-Space series.
