More than 25 years ago - damn, I'm old - I read a multi-generational superhero story that showed how the identity of Black Canary moved from mother to daughter. Nowadays, I'm writing a project that is, in part, a multi-generational superhero story that shows how the mantle of Black Panther has been embodied across decades. And that little bit of DC lore is helping me shape the comic-book history I'm creating.
