Shadowhunters

Long ago, in order to ensure the continued existence of not only humanity but also the Shadowhunters and even the Down-worlders, the Angels and Demons encouraged the practice of Free Use on Earth, essentially turning the human World into a Free Use playground.

When a Shadowhunter turns 18, they go through a maturity that increases their libidos and desirability by great amounts depending on how powerful they are.

When Clary Fray turns 18, she discovers a secret world that her mother kept from her, and that the man who might be her father is searching for something called the Mortal Cock - an artifact of incredible power.
