No Enemy But Time
by Michael Bishop
After a falling out with his parents over their commercialization of his Pleistocene
dreams, John Monegal changes his name to Joshua and finds a way to actually travel to the
Pleistocene where he lives with the Homo zarakalensis, fathers a daughter, and eventually
brings her back to the twentieth century and beyond.
Until the moment of my departure, you see, my life had been a slide show of dreams
divided one from another by many small darknesses of wakeful dread and anticipation.
No Enemy But Time by Michael Bishop (Timescape Books,
April 1982).
