DC History Club: Supergirl: Being Super
My personal take is that Tamaki does a fantastic job building and making you care about the characters in her books. She’s also proving a standout writer of a more conventional superhero book with her current run of Detective Comics. Really like where she’s taking Batman, Huntress and the rest of Gotham in that series.
Also, there’s a copy of Breaking Glass in the house here. I just may have to borrow it.
