They call her... "Mutt"(incomplete)

In a world where pure breeds have always existed lives a girl that was believed to be a miracle child. Daniella Wolfblood is the daughter of the prince vampire and the beta werewolf. While most children that have parents of different races become like one parent or a human Dani became the first vampire-werewolf hybrid. Now she must go to school and learn all she can to defeat the fallen creatures (beasts that were genetically mutated to create a super species) while dealing with her two mates, her jealous brother, and some unrequited love.
