Necessary Passion — Jana Downs

Aidan MacGregor is a vampire hunter who owes his life to a vampire. Despite his reluctance to interact with the vampire who saved his life, it is time to pay his debt. He must travel to Prussia in order to train for the upcoming challenge between Sky and his rival Jessup. Little does he know, the vampire he's made a deal with will pose a greater temptation to his lust than to his anger as the true extent of his role in the conflict is revealed. Sky Engleman is a vampire prince down to his last resort. He didn't expect the child he'd saved would grow up to be the man fate made his alchemy mate, but he will stop at nothing to show Aidan that being with him is the greatest adventure the vampire hunter could ever desire. Aidan wants his freedom, but he also wants Sky. Can they come to a compromise in order to find happiness?
