Norman Conquest 2066 — J.T. McIntosh

A new race would inherit the Earth.

Tormented by neuroses, psychoses, and instability, mankind changed, and two new breeds of humans were born:
Normans - devoid of body hair, quiet, rational, hiding a strange new power. And Sexons - wild, animalistic, with lustful urges.

And each one was convinced it was Earth's true heir.
