Mates but Monsters

Athalia Drakos , well known within the walls of The Main city as 'the secret weapon' and known by The Hierarchy as the one betrothed to the heir to the throne of The Council, goes by only the name Allie having been stripped of every other privilege she had.
Cursed at a very young age by a mother who believed she was the cause of all her misfortunes and later handed to The Hierarchy by a father who only cared about money and power, she lost control over her wolf and became a monster.

Riot Malik, one of the very last night walkers within The Main City and is the most wanted serial killer with the biggest price pinned on his head, lives on the run and trusts almost nobody. At least most think he's on the run.
Having grown up with a single father who was notorious and taken in for his deals with The Opposers who led to The Bloodshed, he was tortured until his ray parted with his silhouette and he remained with only the darkest part of himself that hoped for nothing but vengeance. But that was millennia ago and there are even rumors that he's dead. Except he's not. He's been waiting for the right time.

What happens when two broken souls, two beasts, turn out to be mates?
Will The Council and The Hierarchy survive or will they all go down ONE by ONE?
