There is now a link to Batman Unauthorized -- edited by Denny O'Neil -- on the toolbar on the right. The essay I have in the book is a nicer version of three posts printed here on Dark Knight Strikes Again, Batman/Spawn, and All Star Batman and Robin the Boy Wonder. My overall point is that these works are secretly awesome, and that Frank Miller is a misunderstood genius in the iconoclast mode of William Blake. BenBella makes a pretty good product and I am sure that the other contributers are equally sharp.
At this point I have no other essays in the que at BenBella so this is the end of my BenBella "Quadrilogy" until they put up another call for papers.
