Joe Haldeman

The Earth's leaders have drawn a line in the interstellar sand—despite the fact that the fierce alien enemy that they would oppose is inscrutable, unconquerable, and very far away. A reluctant conscript drafted into an elite Military unit, Private William Mandella has been propelled through space and time to fight in the distant thousand-year conflict; to perform his duties without rancor and even rise up through military ranks. Pvt. Mandella is willing to do whatever it takes to survive the ordeal and return home. But "home" may be even more terrifying than battle, because, thanks to the time dilation caused by space travel, Mandella is aging months while the Earth he left behind is aging centuries.

2043 A.D.: The Ngumi War rages. A burned-out soldier and his scientist lover discover a secret that could put the universe back to square one. And it is not terrifying. It is tempting...

Joe Haldeman "has quietly become one of the most important science fiction writers of our time" (Rocky Mountain News). Now he delivers a provocative novel of a man who stumbles upon the discovery of a lifetime-or many lifetimes. Grad-school dropout Matt Fuller is toiling as a lowly research assistant at MIT when, while measuring subtle quantum forces that relate to time changes in gravity and electromagnetic force, his calibrator turns into a time machine. With a dead-end job and a girlfriend who has left him for another man, Matt has nothing to lose taking a time machine trip himself-or so he thinks.
