(From the publisher):
One day Duncan MacElroy was just an average engineering student at Arizona State University, the next he was holed up in a cabin near the Grand Canyon, on the run from deadly Neanderthals carrying laser pistols.
The only things that saved him, it seems, were his quick wits, a fast woman, and a Paratime shuttle—whatever that was.
And the adventure had only just begun!
