Servant Series by L.L. Foster

Urban paranormal fantasy featuring Gabrielle Cody: Servant. Slayer. Seducer. Gabrielle Cody has the ability to see the demons among us as they really are-and the responsibility to destroy them. She can't allow anyone to get in her way, even the magnetic Detective Luther Cross. Sensing a malevolent presence watching and stalking her, Gaby is drawn again and again to an abandoned hospital surrounded by an aura of sickness and suffering-and unimaginable evil.

Gabrielle Cody has accepted her destiny as God's warrior, charged to destroy all evil, but she wasn't prepared to see Detective Luther Cross ever again. He's the beacon of reality in her life, the one thing that makes her feel human, like a real woman. But Gaby must resist involvement with Luther now, for she is protecting streetwalkers. Her life of retribution is far too dangerous, and this time, it's not just their hearts that won't come out unscathed.

Gabrielle Cody is a paladin?God?s enforcer on earth. But she?s not sure she can endure the life of a holy warrior. Her relationship with Detective Luther Cross is under constant strain already, and its going to get worse. There is a monster feeding off of human blood, flesh, and souls and Gaby must stop him. But her passion for Luther distracts her from the terrible connection she has with her quarry?and the creature?s desire to devour her.
