Duncan MacElroy was an ordinary engineering student before he went out for a six-pack of beer one night and never came back.  Instead, he found himself embroiled in a war for the dominance of Paratime, as well as defending our own particular version of Earth from predators on both sides of the battle lines.  For he quickly discovered that "parallel universes" aren't, and that a single individual can make all of the difference in the worlds!
