MTV has an exclusive look at a whole bunch of BLACK CANARY stuff, along with commentary from Brenden Fletcher and myself. Check it out. It includes a few pages of lineart from the 8-page preview that'll be available for free online later this month.
Also, since people were asking -- I won't be taking pre-orders for commissions at this summer's conventions, but I'll sign and sketch as I can. $80 busts and blank covers. There will be merch, probably.
