In a future, caste based society a man is caught leading a double life and marrying outside of his caste. In exchange for staying with his family, he agrees to travel back in time to prevent a particular caste from ever coming into existence. The critical event that needs to be changed is the Cuban Missile Crisis.

I read the book in the mid to late 90s. I believe the cover art was a picture of a globe with a man running on top with prism like rays of light coming from where his foot touches the globe.

    And for the millionth time... When did you read this? How old do you think the book might be? Can you remember anything about the cover?

  • @FuzzyBoots I don't see anything in that discussion that looks like what I'm looking for. Although, I think some of those titles have turned up in my previous attempts at googling.

I think this is Dead Morn by Piers Anthony (1990). From Goodreads:

In the 25th century survivors of the nuclear war must live underground. Their actions must be regulated. Their passions must be controlled.

Love is a crime, and when a man dares to take a lover of his own choice, he must be punished.

It's time for a change and the only way to alter this grim future is to journey back to the past...

And change a few small details.

The front cover matches your description too:

    Hi, welcome to SF&F! Based on the description, you might be right, but you could make this a better answer by showing how this book matches the details in the question.

  • "With humankind surviving underground in the twenty-fifth-century's last city, a courageous man journeys back in time into Cuba's history to try to alter the past and stop the worldwide conflagration that would leave Earth a nuclear wasteland." Is part of the description for the book in various sites. Oct 23, 2018 at 9:06
  • That's it. Thanks, this has been bugging me for years.
