Compare The Secret History of Elizabeth Tudor, Vampire Slayer

On the eve of her coronation, Elizabeth Tudor is summoned to the tomb of her mother, Anne Boleyn, to learn the truth about her bloodline—and her destiny as a Slayer. Born to battle the bloodsucking fiends who ravage the night, and sworn to defend her beloved realm against all enemies, Elizabeth soon finds herself stalked by the most dangerous and seductive vampire of all. He is Mordred, bastard son of King Arthur, who sold his soul to destroy his father. After centuries in hiding, he has arisen determined to claim the young Elizabeth as his Queen. Luring her into his world of eternal night, Mordred tempts Elizabeth with the promise of everlasting youth and beauty, and vows to protect her from all enemies. Together, they will rule over a golden age for vampires in which humans will exist only to be fed upon. Horrified by his intentions, Elizabeth embraces her powers as a Slayer even as she realizes that the greatest danger comes from her own secret desire to yield to Mordred . . . to bare her throat in ecstasy and allow the vampire king to drink deeply of her royal blood.
