The Crimson Princess (The Ravengale Chronicles, #1)

For the rulers of Ravengale, there is only us and them...until the rule of law becomes the path to destruction.

As princess of Ravengale, Satima is bound by her father's rule to sit back as others compete in the Challenge and watch the champions travel to the human realm to shelter the innocents from the monsters of the Third World. But the Book of Life dictates a path for her that defies the laws of Ravengale and she temporarily vacates her throne to fight for humanity, a choice that will change the destiny of her world and beyond.

As Satima is thrust into a tragic battle, death will touch her in the most intimate of ways, driving her into the path of her father's enemy, the ancient and powerful vampire king. Toren is as gorgeous as he is a ruthless leader, and despite Satima's caution, the vampire makes her blood run hot, and her body hotter. But in the throes of passion, there is a dark history between their worlds, a darker one between Toren and her father. One wrong move, and everything Satima has known and loved will be shattered.

***
In the vein of Buffy the Vampire Slayer and Reign where the princess is a warrior, the fae are inconsequential, zombies are real, and vampires and druids are enemies of the court. That is until one vampire, the king himself, seduces the princess into risking all for him.
