The Old Man’s War Series

At 75 years old, John Perry is after a fresh start - so, naturally, he joins the army. Earth's military machine can transform elderly recruits, restoring their lost youth. But in return, its Colonial Defence Force demands two years of hazardous service in space. This is how Perry finds himself in a new body crafted from his original DNA. A genetically enhanced and upgraded new body, ready for battle. But upgrades alone won't keep Perry safe. He'll be fighting for his life on the front line as he defends humanity's colonies.

Three hostile alien races have united against humanity, determined to halt our expansion into space. The mastermind behind this lethal alliance is a traitor - Charles Boutin. He was a Colonial Defence Force scientist with access to their biggest military secrets. Now the CDF's only hope is to discover Boutin's plan. Trouble is, Boutin's dead. As a supersoldier created from Boutin's own DNA, Jared Dirac may have answers.

John Perry was living peacefully on 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 the planet, they discover they've been betrayed. For this colony is a pawn in an interstellar game of war and diplomacy. Humanity's Colonial Union has pitched itself against a new, seemingly unstoppable alien alliance dedicated to ending all human colonization.

Jane Sagan: Soldier. Killer. Lover. Dreamer. In John Scalzi's best-selling Old Man's War series of science-fiction novels, we see this warrior woman as the other characters see her - silent and strong, from the outside. But now The Sagan Diary shows us Sagan from another point of view: her own, as she prepares to leave military life and join her new husband and adopted daughter on a colony world.

The people of Earth now know that the human Colonial Union has kept them ignorant of the dangerous universe around them. For generations the CU had defended humanity against hostile aliens, deliberately keeping Earth an ignorant backwater and a source of military recruits. Now the CU’s secrets are known to all. Other alien races have come on the scene and formed a new alliance - an alliance against the Colonial Union. And they’ve invited the people of Earth to join them. For a shaken and betrayed Earth, the choice isn't obvious or easy.

Humans expanded into space...only to find a universe populated with multiple alien species bent on their destruction. Thus was the Colonial Union formed, to help protect us from a hostile universe. The Colonial Union used the Earth and its excess population for colonists and soldiers. It was a good arrangement...for the Colonial Union. Then the Earth said: no more.
