In the Realm of Divinia, there are two kingdoms- that of the faeries, the Sallow Kingdom, and that of the vampires- the Nightingale Dominion. Faeries and vampires have been at war since the beginning of time, and hostility continues to run rampant between the two nations. When Dorian Nightingale, the vampire crown prince, is accused of killing a member of the Sallow royal family, war is imminent. He's forced to accept the help of his mortal enemy, faerie heiress Ainsley Sallow, to prove his innocence and prevent the total damnation of both their worlds.
