The heroine is a half-blood vampire still wet behind the ears. She's got her sights on a certain knight, and schemed up a plan to dine on his blood... She'll slip him some drugs and have a delicious feast to enjoy! Nothing could go wrong, right? Wrong. The mixture of drugs and the bewitchingly erotic nature of blood sucking causes the knight to transform into his werewolf form... and turn the tables on the heroine!
