During the interstellar war with the Taurans, William Mandella climbs the ranks from private to major. While the war itself only lasts a few years from the perspective of the troops—since much of their time is spent traversing wormholes well beyond the speed of light—nearly 1,200 years passes on Earth.

While on a mission early in his career, Mandella falls in love with fellow soldier Marygay Potter and the feeling is mutual. After Potter is nearly killed during their final tour, the army grants the pair a discharge on Earth. However, Mandella and Potter soon discover that retirement is not an option. Only one job opportunity is made available to them—return to the war.

In their next campaign, both Mandella and Potter each lose a limb and are sent to a world known as Heaven to regenerate. Mandella is then promoted to Major and Potter to Captain—but each are assigned to separate companies.

After saying their final goodbyes, Mandella takes command of a Strike Force headed to Sade-138, while Potter was assigned to fight the Taurans elsewhere. Mandella fears that they will never see each other again.

In order to qualify for command, Mandella must undergo a deep-sleep learning process during which his mind is filled with facts and theories from Earth’s military history. What’s more, Mandella finds himself in command of a platoon comprised completely of homosexuals. Heterosexuals, while tolerated in human society today, are now considered queer.

ForeverWar is a satisfying hard-SF novel that presents a unique and often candid view of futuristic military life and the possible drastic changes that might occur in Earth’s culture given 1,200 years. While the Taurans are treated lightly and never developed as anything more than an alien menace, Haldeman does an admirable job detailing the battle scenes and showing how the enemy improves their tactics and weaponry with each successive confrontation.

Most of all, it was Mandella’s experiences with his fellow soldiers, his struggles with changing times (especially on Earth), and his ability to adapt and survive that kept me intrigued.
