The Werewitch Of Wayne Manor

Melody Wayne is a lot of things.
An alien, a witch, and a werewolf.
Bruce Wayne's adopted sister.
And the only person in Gotham who can terrify Batman and comfort him in the same breath.
Their lives at Wayne Manor are already complicated enough-by night they fight monsters and mobsters, and by day they're trying to be something like a family. Over time, Bruce and Melody's bond twists into something deeper, something forbidden...and impossibly hard to ignore.
Together, they take in broken kids and turn them into Robins: acrobat-turned-orphan Dick Grayson, angry street kid Jason Todd, brilliant detective Tim Drake, and assassin heir Damian Wayne. Piece by piece, the manor fills with laughter, secrets, and the fragile hope of a real home.
But there's one truth that sits between them like a loaded gun.
Bruce knows exactly what Melody is.
Her rare branch of magic runs on blood-murder committed in cold blood, again and again, to keep her powers alive. If she stops, the consequences could destroy her and everyone she loves. If she continues, it means Batman has to live with the one line he swore he'd never cross...written in the hands of the woman he loves.
This is the slow burn story of how Batman falls in love with the monster in his own manor-and chooses her anyway.
