Ayckbourn, Alan - The Divide

A lethal STD pandemic is annihilating humankind. Women carry, exposed men perish. Within a few generations, adios folks.
Solution: divide the genders. Men in the North, women in the South. Wait for the disease to die out.
Generations play out; now young male Eilhu and female Giella discover hormones and libido.
Epistolary novel, set in the near future, predominantly in the female South, is NOT a dystopian saga.
Society works fairly well, although there are glimpses of discontent. Attitudes are divided between Orthodox, Moderates and Progressives.
Being epistolary, the narrative is carried by diaries, letters and memorandums.
Because so much of this is told by young Soween, I am putting this into Young Adult reading, despite some of the spicy activities.
Main characters are teenagers, yet they seem like teens from the 1940’s or much earlier.
I had trouble buying them.
There are four seasons. Winter, Spring, Summer, Autumn. Each season has 30 days.
After 200 pages, the adults predominate and the energy boosts.
By using different fonts, each character their own handwriting. That was a creative touch.
Fans of the playwright might be tempted, but this not a comedy of manners. It is an old-fashioned, VERY old-fashioned love story.
