Wolves at Heart

Big brother Jason and little sister Marinette Todd are not normal people, but have a dangerous secret: they are werewolves.

Separated at a young age while living in the streets of Gotham, the Todd siblings fight to survive in a world where everyone hates half-blood hybrids like them. Jason's adoptive family, the Wayne's, have no idea about anything of Jason's past or dark secret, while Marinette's adoptive family, the abusive Dupain-Cheng's, know everything and hate her for it.

As a result of their hatred of Marinette, the bakers forbid her to go out as her wolf or tramsform, and they do not take care of her by any means, only making her life terrible to the point where she's afraid of herself.

Then Lila comes and makes her life even more of a living hell to where she wants nothing to do with life and is as broken as anyone can come, especially when the class finds out her secret and are always hunting her down.

Mari eventually has had enough with Paris, so she runs away and leaves the country, running back home to Gotham, where she lives on the streets and is quickly having people hunting her for money and her fur.

Will Marinette find Jason and be saved? Will he be able to help his little sister, or will they both have to depend on the Kent family for protection against Gotham and Paris?
