Xenobiosis:
communal life, such as that of ants, in which colonies of different species live together but do not share the raising of the young. — xenobiotic, adj.
Being told to be different from other people is a normal thing, but what happens when your differences set you apart from others in a bad way? Lilith Vautrin is different, but her uniqueness doesn't come with positive connotations. And to make matters worse, she's a half breed hybrid of two of the most feared species on Arlovia: Demons and Angels. Her people are hated and made out to be less than human (which in a literal sense of the word they are), so how can one girl, outcast even among her own people, find a place for herself in a world where its normal for supernatural species fight for dominance of the planet?
