Demoness

Cassandra is a very modern, if Satanic, exotic Dancer. Little does she guess what adventure Satan has in mind for her in Medieval Paris...
Before Cassandra stepped from the magic circle in the bowels of the Magister's palace, she learned two things: that she had been conjured to seduce a Priest and that she really was a Demoness obedient to the will of the Magister that conjured her.
She discovers that her demonic powers had a bloodthirsty will of their own, and that the Priest was a member of the deadly Spanish Inquisition who had killed all the women previously sent to seduce him.
