Isabelle is a witch princess and far from impressed when she is told that she must marry a vampire prince in order to secure a strategic alliance with the undead; without help from the vampires, witch covens face extinction at the hands of the fraklov demons. The same is true for the vampire covens.
Isabelle agrees to the marriage for the sake of survival but she resolves to fight the vampire prince every step of the way. That resolve is severely tested, however, when she sneaks into the prince’s room to discover exactly what she is up against and sees Prince Lucian for the first time.
Prince Lucian is also against the arranged marriage and extremely reluctant to be marrying a witch. When his vampiric sense of smell detects an intruder in his room, the prince is highly insulted and is determined to locate and punish the intruder. His plans for the intruder change though, when he meets the princess and discovers it is her. Suddenly marriage to the witch doesn’t seem quite so distasteful.
