Bound By The Blood Moon

Darren King is as crude as they come. A tribrid - mainly vampire, partly werewolf, partly witch and bathed in angel blood. Wat hero. First of his kind. One and only of his kind. And only through conception can there be others. But he has a problem.
Although respected in the vampire and werewolf clans, he won't be giving worthy "vessels" (women to birth his offspring). And not all tribes are compatible with his blood especially the humans. He's running out of time. Even with immortality and the ability to live without blood, he can't birth children forever. He is tied to the blood moon which is 10 years away. After that, all his offspring would be mere vampires.
