The Centauri Survivors — Andrew J. Chamberlain

When a habitable planet is discovered just four light-years from Earth, governments and private corporations rush to build a ship to take the first humans there. But only a few of the colonists wake up from cryosleep after the sixty-year journey, and as their ship comes into orbit around the new planet, they find themselves surrounded by death.

As the survivors scramble to make sense of what has happened, they find their own lives under threat, and, pursued by their enemies, they escape to the surface of the new planet. Caught between their human adversaries and whatever the planet throws at them. the survivors fight to stay alive, as circumstances drive them towards a final, deadly confrontation.
