Unfortunately, the Rakshasa are currently winning the battle, as the Light Ones are not fertile. Only one type of Light One, exceedingly rare females called Chala, are able to produce offspring. The Rakshasa know this, and have managed to nearly decimate the population.
Enter Gavin Rowan, a cursed Rakshasa who believes he is a Light One. He feels all his Rakshasa urges to kill, but has been cursed to protect the Light Ones instead.
Throw Sydney Amataya into the mix. She is a Chala--except she doesn't know it. At least not until Gavin saves her from a Rakshasa attack and then declares her as his mate.
But that's not how Sydney operates. Encouraged by her cross-dressing Fate, William, she refuses Gavin's claim. If he wants to mate with her--once she gets over the shock of discovering this supernatural world, that is--he's going to have to woo her, impress her, wine and dine her. Romance her. She deserves no less, end of the world be damned.
