I cannot compliment this comic universe enough. I have read comics for quite awhile and have read all the classics, long Halloween, hush, court of owls, etc. This series should be considered in that reign. Sean Murphy has completed two volumes so far with a third coming on the way and two spin offs. One that is currently on-going.
The general premise of volume one is Batman is viewed as the antagonist for going to far and Joker is viewed as the hero because he is reverting back to a sane person. Both volumes have eight issues and take risks with major characters dying or having different versions of themselves. I really love this series even though volume 2 wasn't as strong as volume 1 i'd highly recommend it.
