And it's got Jim Lee/Scott Williams doing the art.
Jeff Loeb is the writer. Worth looking into even if you don't read Batman comics; there's nothing you need to know about past issues when you read this story; it's all self-contained and done very well in that regard. You get appearances from Catwoman, Robin, Nightwing, Harley Quinn, The Joker, Killer Kroc, The Riddler, Poison Ivy, Superman, and more.
I guess you could say I'm a big Hush fan. Bought both of the hardcover graphic novels and am working on getting most of the toys...DC is doing a Hush action figure line and IIRC Series 3 is about to come out.
