Eternally Theirs by Eden Bradley

There is nothing in this world more dangerous than a vampire who has lost his will to live.
Except perhaps one who has lost his sanity. And for too long, I have run the risk of losing both.
Until salvation stumbles its way into my club, in the form of a pair of newly minted vampires. Mercy and Deo. Alone. Terrified.
Intoxicating.
They call to me, their innocence shining like a beacon into the meaningless void of my existence.
When Mercy’s life is threatened, the darkness inside of me is the only weapon I have to protect her. But saving her may mean sacrificing the life we’ve just begun to build.
And losing myself to the madness waiting in the wings.
