John Scalzi’s The Last Colony is the third in The Aged Man’s War series.

They need to save themselves – or pass away trying.

John Perry was living peacefully using one of humanity’s colonies – until he and his wife were offered an opportunity these ex-supersoldiers couldn’t resist. To come out of retirement and lead a new frontier world.

However, once on earth, they discover they are betrayed. For this colony is normally a pawn within an interstellar video game of battle and diplomacy. Humanity’s Colonial Union has pitched itself against a new, seemingly unstoppable alien alliance, dedicated to ending all individual colonization.

As this competition rages above, Perry problems to maintain his terrified colonists alive on the surface below – despite dangerous interstellar politics, violence and treachery. And the planet has yet to reveal its own fatal secrets.
