"I believe in something highly unusual for most people - I believe in the supernatural world." There's a rule. A rule that one must obey no matter what the odds. A rule that one could be punished severely for breaking it; because when this rule is broken, the balance will be disrupted. It is said that the rule was made for avoiding the possibility of a stained blood, for the pure-bloods are so strict about keeping their kind what it is, and rejecting every means of a new race of mixed-bloods, but no one really knows the actual reason - other than the Goddess herself. And the rule? "You must not fall in love and mate with a human". But everything happens for a reason. And Lilith Lane's life is about to change as she meets the love of her life in a blue moon.
