The Forbidden Dragon King by Rosemary A Johns

A Dragon King. A secret princess. And the revenge he burns for.

After the murder of his brother by vampires, Aurelius, the most powerful dragon warrior in the Shadow Kingdoms, blazes with desire to destroy his enemy.
All he needs to do is capture the monstrous Vampire King’s omega, Freya.
His fated mate.
She doesn’t know who she truly is or her own magic. She’s a mistreated outcast in the wolf shifter kingdom, until Aurelius swoops in and saves her. He flies her away to the merciless Shadow Court.

A cunning thief, she trains at the dragon-rider military academy with strict rules, intrigue, and deadly secrets.
She’s only meant to be a pawn in his war. But when he touches her, his whole world sparks to flame. Yet he’s forbidden to bond with anyone.
He doesn’t know that he’s risking love igniting between her and his other prisoner, the masked Fae King who has become her protector.
But he can’t allow himself to care. He’s set to sacrifice her in his plot to finally destroy the last Vampire King.
But if he does, will his cold heart be burned to ash?

Three villainous kings. One strong heroine. And an epic love that could burn an empire.
