Gail Simone is on Tumblr, sharing some insight into her work, among other things.
Honestly, if you are not reading Secret Six and Birds Of Prey, what exactly are you reading comics for? Funny, whip-smart writing that goes right to the good place, every time. The last arc in Secret Six was just jaw-droppingly good. Seriously, I read the whole thing with my mouth agape. A-freakin’-mazing.
