This is about a two-book series that was likely written between 1975 and 1999. The survivors of a planet lived on a narrow inhabitable strip of the planet. On both sides there were less habitable areas. On one side lived mutants who were like vampires and werewolves. In the strip lived the main characters in a town, one a strongman, one a mind reader whose wife was a healer and operated a clinic, one a blind woman who could see the future. There were several towns. The mind reader has a female child whose skin changed colors and also had a son. The leader of the werewolves had a son who killed those living in the town where the main characters lived. When the blind woman got her sight back temporarily, she lost the ability to see the future. The healer’s wife died near the end of the book and the mind reader decided to move to another town where his children had previously moved.
