Knight of Night

Aisha, the mother of all vampires was loved by Fallen Angel Luzbel, Archangel Michael and Death itself. But she chose Luzbel and he became the first Chevalier, a werewolf and her protector. 

In a battle with heaven, Aisha died protecting her fellow vampires. 

300 years later, one of her sons called upon her and offered her three possibles candidates for her to reincarnate. One of them, newborn Allyssa Gontmacher, is kidnapped by her mother and lived a human life. She grew up as Mia McAdams until one day she and her brother Michael are attacked by white shadows and are saved by a huge black wolf who turned to be an otherworldly handsome man called Lionel. 

He told her the true about her origins and that she is the third candidate of the Queen and for that she has to live aboard the Hail Aisha Academy where he would be her Chevalier, a lot like a personal butler.
