«Breaking Fate» by Georgia Lyn Hunter

An immortal without a soul is bad enough. But when his only tether to remaining honorable is his addiction to bone-crushing pain, it makes Blaéz a dangerously loose cannon. A Guardian sworn to protect mortals from supernatural evil, Blaéz straddles the edge of darkness as his needs grow. When a good deed brings him to the doorstep of a female unlike any other, one whose touch ignites emotions long lost in the hellish pits of Tartarus, he’s determined not to lose her. She belongs to him. But she’s human. Forbidden. And bringing her into his life may just destroy them both. Darci Callahan has given up on love. When a lethally handsome stranger suddenly appears late one night, she finds herself inexplicably drawn to the captivating man with the pale, empty eyes—a man who awakens in her a desire she never believed possible. Except Blaéz brings more than unexpected passion to her life, he brings danger. In this treacherous new world of gods and demons, Darci soon discovers a heart-shattering truth and the twisted games the gods play. Caught in the crosshairs, she’s forced to accept that, sometimes, no matter how much you love someone, you have to love them enough to let them go…
