Nightwalker

Ren Nightwalker is not what he seems. His eighteen-year-old appearance is just a façade. He's actually a three-hundred-year-old vampire prince with one job, to save his people.
In his world, they fight for a future. One against a monster with the power of resurrection, one who controls the dead; a necromancer. In the human world, monsters are hunted by a powerful organization comprised of believers from religions across the world.
When Ren learns that both of their enemies have teamed up to take them down, their only chance to win the war comes in the form of two stones, thought to be merely a myth, the Sun and Moon Stone. Apart, the stones are already powerful. Together, they have the power to turn the tide. This quest of a lifetime will take Ren and his companions all over the world, and force them to encounter more than one enemy.
To make things worse, Ren has a secret that no one knows. His refusal to drink blood is literally killing him, and if he doesn't find an alternative, Ren will die long before they can win the war. His only hope is that they find the stones before that.
Can Ren find the stones while fighting two enemies at once and hopefully turn the tide in the war? And can they do it before he meets his eventual demise?
