Escape in Venice

Antonia Correlli, is relatively young vampire who still learns to master her special abilities as a succubus. As such, she does not only feed on blood like ordinary vampires, but can also feed on humans' sexual passions, draining them of their energy and powering her unique abilities.
Antonia is invited by her incubus friend and mentor, Count Emilio, to 18th century Venice in order to help him with a delicate matter, a young lady the count desires, but who does not respond to his incubus magic as she should. Antonia, tasked to find out what makes this woman resistant to the count's advances, must learn to master her own magic as well as find a way to save her friend's beloved one from a great danger.
