TL;DR: Physics student William Mandella is drafted into an elite force to fight the Taurans, an alien species humans barely understand. Because soldiers travel near the speed of light, a few months for them means decades or centuries on Earth. Each time Mandella returns home, Earth has changed beyond recognition, and the war seems more pointless than ever.

What Happens, Part by Part (Contains Spoilers)
Drafted
In 1997, Mandella and other highly intelligent young people are drafted into the United Nations Exploratory Force after a human ship is supposedly attacked by aliens called Taurans. They train in brutal conditions on the frozen planet Charon, where many recruits die. Soldiers travel through “collapsars,” a kind of shortcut between stars, and the time effects of near-light speed mean years pass at home.
First battle
The soldiers land on a Tauran planet and attack a base. The Taurans hardly fight back, and the humans, under hypnotic conditioning, massacre them. Mandella is shaken. When the unit returns to Earth, twenty-two years have passed for those at home, even though they have aged only two.
A changed Earth
Earth is now crowded, violent and expensive. Governments control almost everything, and people struggle to find meaning. Mandella and Marygay feel like strangers. Mandella's mother dies. Unable to fit in, they re-enlist, hoping at least to stay together. But the army separates them, sending them on missions that will place centuries between them.
A stranger in his own army
Mandella is promoted to major and given command of a unit. Centuries have passed, and Earth's culture is completely different. Many of his soldiers speak a new form of English, and he feels like an outsider. They fight a long, bloody battle on a distant planet where both sides use slow weapons because of a field that stops fast ones. Many soldiers die.
The end of the war
When the battle ends, Mandella learns that the war is over. It lasted 1,143 years and began from a misunderstanding: the Taurans had not started the attack. Humanity has evolved into “Man,” a single cloned collective that can communicate with the Taurans. Marygay, who used near-light travel to wait for him, is alive. They reunite on a planet for veterans and start a family.
5 Key Takeaways
- War can rest on lies and misunderstandings.
- Soldiers often return to a world that no longer fits them.
- Time dilation turns distance into a kind of exile.
- Military systems can treat people as tools.
- Love can endure across centuries.
Ideas Worth Remembering
These are paraphrased, not direct quotes:

- Change at home can be as shocking as battle.
- Communication could prevent many conflicts.
