A Curse In The Dark - The Four Houses, #3

The Four Houses descend into chaos, and two unlikely heroes-a human nurse and a vampire mercenary-are trapped in the depths. Pawns in a bigger game. Predator and prey. Unless they defy their natures and change the fate of their worlds. All Laine O'Callaghan wants with New Orleans is to locate the thief that stole from her and reclaim her family's heirlooms. Then the Irishwoman's bus is attacked and she's kidnapped by vampires.
Bleeding vampires! Monsters are real, and her thief is their boss. Now she's trapped in an underground lair, being offered up as a prize to the strongest fighter. Vampire Mitrick Black is missing an eye, an arm, and a chunk of his leg-and he won't back down from a fight. Brutally injured, the gun-for-hire has one chance to survive: reclaim his position at his evil employer's by winning a human blood-servant. A human whose fierce spirit makes him want to protect her at any cost. Yet Mitrick swore an oath to the werewolf who spared his life-and there's no human servant in that promise.
Especially one who spikes his hunger at every turn. Laine should be focused on the mystery behind her family's heirlooms. Yet she can't deny the fire that consumes her at Mitrick's touch. In the magic tunnels beneath New Orleans, unexpected love is their greatest strength-and their greatest weakness. When her quest for answers lands them both in the crosshairs, can they survive a curse in the dark?
