The Last Colony — John Scalzi

John Perry, the hero of John Scalzi's bestselling Old Man's War, has retired with his wife and daughter to one of humanity's many colonies. It's a good life, but something's . . . missing. When John and Jane are asked to lead a new colony world, they jump at the chance to explore the universe once more.

But nothing is as it seems. Perry and the new colony are pawns in an interstellar game of diplomacy and war between humanity's Colonial Union and a new, seemingly unstoppable alien alliance that has demanded an end to all human colonization. As these gambits rage above, on the ground Perry struggles to keep his colonists alive in the face of threats both alien and familiar.

For his family's survival, and everyone else's, Perry must unravel the web of lies, half-truths, and deception spun around him and uncover the colony's shocking true purpose -- lest it become, truly, the last colony of the human race.
