Joe Haldeman writes science fiction about war, time, identity and the gap between military experience and civilian society. The Forever War follows soldier William Mandella through an interstellar conflict in which relativistic travel causes centuries to pass on Earth while he experiences only years, making every return home more alienating. Forever Peace is a separate novel about remote warfare, technology and the possibility of stopping organised violence. Haldeman's own Vietnam War service informs the sceptical treatment of military institutions found in much of his work. His prose is direct, fast and idea-led rather than ornate. His books fit military science fiction, anti-war SF and future-war novels shaped by technological consequences. The Forever War is the central entry point, using relativistic time not only as a science-fiction device but as a way to make returning home increasingly difficult. Read more Less
