The Heir by V.K. Ludwig

In 2091, the Clans and the Districts struggle to rebuild society, after a chemical accident has wiped out most of the female population.

At the Clans, women are as much treasured by some men as they are threatened by others — who are willing to put their morals aside to get their hands on something so rare and precious.

Nix, clansman and heir to the dying chieftain, travels to the Districts, where sexual suppression keeps women safe while IVF favors the birth of girls. His plan is simple: bring about a merge between the two factions.

The council of the Districts is quick to assign Kenya as his neutral mediator, in order to help bring negotiations along.
But after losing her father at the hands of a clansman twenty years ago, Kenya is everything but neutral.

She knows only one truth: the lack of control over desire is clearly a clansman trait. One she doesn’t share, no matter how tempting a man like Nix might be — and she is out to prove it!

But Kenya quickly realizes Nix doesn’t fit in with her version of the truth. Can the aspiring chieftain help repair Kenya’s trust in men like him? After all, he carries a dark secret. One that overshadows his very existence, threatening to put everything he loves at risk: including Kenya.
