Time Slave — John Norman

Dr. Brenda Hamilton—a PhD mathematician from Caltech—is beautiful, though she does not know her true beauty. She is a woman, though she does not know her true womanhood. Deep within herself she is sensual, though her senses have been dulled by this modern world. Hamilton has come to Africa to work under the brilliant Danish scientist Herjellsen, a man who speaks of reaching the stars. But what does the ancient stone axe laying on his lab table have to do with space travel? Soon it becomes clear that Herjellsen’s experiment is much larger than Hamilton or Herjellsen or even space travel itself. It is about correcting a mistake made tens of thousands of years ago in human evolution.
