The Battle Lord's Lady. The Battle Lord Saga, #1

Three hundred years in the future, mankind still is trying to survive the Great Collision that changed the earth forever. People live in pockets of civilization called compounds, battling the elements and the mutations which have developed over the centuries, trying to live and survive day by day. Yulen D'Jacques is the Battle Lord of Alta Novis. His duty is to keep his compound and his people safe, which means yearly sweeps of the area to remove any mutated men and animals from encroaching.
Atrilan Ferran is Mutah, a mutant warrior and huntress trained to protect and defend her home from Cleaners, the "normals" who invade the forests to slaughter everything and everyone who gets in their way. They never anticipated the day when their hearts would collide, challenging and changing everything they thought was the truth. Leading them to the day they would have to prove their love for each other to man and mutant alike.
