Eleazar by Lynn Hagen

When Andrew is offered an interview with the mysterious Eleazar Bancroft for a job as his personal assistant, he’s overjoyed. But when he gets the position, he soon realizes that there is more going on than meets the eye. He is ordered to reside at the estate but isn’t allowed to roam the premises. Despite discovering that he’s in a house filled with vampires, Andrew decides to stay because of his overwhelming attraction to Eleazar, even though the rational thing to do would be to flee from danger and never look back.
After the fiasco with Felix, Eleazar isn’t sure he wants another human servant—until he meets Andrew. An inexplicable magnetism draws them together, and Eleazar can’t stop himself from giving in to his desires. But someone wants Andrew dead, and it’s up to Eleazar to eliminate all threats toward his pregnant mate, even if he has to wipe out his entire coven to keep Andrew safe.
