The Old Man’s War Series

John Perry did two things on his 75th birthday. First he visited his wife's grave. Then he joined the army. The good news is that humanity finally made it into interstellar space. The bad news is that planets fit to live on are scarce—and alien races willing to fight us for them are common. So: we fight. To defend Earth, and to stake our own claim to planetary real estate. Far from Earth, the war has been going on for decades: brutal, bloody, unyielding. Earth itself is a backwater.

The universe is a dangerous place for humanity—and it's about to become far more dangerous. Three races that humans have clashed with before have allied to halt our expansion into space. Their linchpin: the turncoat military scientist Charles Boutin, who knows the CDF's biggest military secrets. To prevail, the CDF must find out why Boutin did what he did. Jared Dirac is the only human who can provide answers—a superhuman hybrid, created from Boutin's DNA, Jared's brain should be able to access Boutin's electronic memories.

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.

Retired from his fighting days, John Perry is now village ombudsman for a human colony on distant Huckleberry. With his wife, former Special Forces warrior Jane Sagan, he farms several acres, adjudicates local disputes, and enjoys watching his adopted daughter grow up. That is, until his and Jane's past reaches out to bring them back into the game — as leaders of a new human colony, to be peopled by settlers from all the major human worlds, for a deep political purpose that will put Perry and Sagan back in the thick of interstellar politics, betrayal, and war.

How do you tell your part in the biggest tale in history? I ask because it's what I have to do. I'm Zoe Boutin Perry: A colonist stranded on a deadly pioneer world. Holy icon to a race of aliens. A player (and a pawn) in a interstellar chess match to save humanity, or to see it fall. Witness to history. Friend. Daughter. Human. Seventeen years old. Everyone on Earth knows the tale I am part of. But you don't know my tale: How I did what I did—how I did what I had to do—not just to stay alive but to keep you alive, too.

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.
