Years ago, I read Kevin J. Anderson's "Last Days of Krypton" and was quite impressed in his vivid story-telling and how he painted a picture of Krypton's destruction and how he handled characters (in depth) like Zod, Aethyr (Ursa) and Nam-Ek (Non), Zor-EL, Lara and Jor-EL. Very good read of sci-fi elements that I think any Supes fan would enjoy that is interested in classic Kryptonian villains and the sheer brilliance of the EL family.
I was browsing Barnes and Nobles and came across Kevin J. Anderson's fresh installment in his superhero writings "Enemies & Allies"; set in the era of 1950's. A Superman/Batman meetup during the Cold War. The description is as follows:
"It was time of international tensions, a time of hope and fear---- when rock 'n' roll, UFO's and the Communuist menace preoccupied America; the first time in history when human beings had the power to destroy the world. It was when heroes were needed more than ever. Evil is loose in the world. As the United States and the Soviet Union race to build their nuclear stockpiles, two extraordinary men are called upon to form an uneasy alliance. Studies in opposites----shadow and light---- a Dark Knight and Man of Steel must overcome their mutual distrust to battle a darkness that threatens mankind. And when the paths of these titans cross, a bold and exciting new chapter of history will be written....and nothing will ever be the same."
If it's anything to the imagination of "Last Days of Krypton" then this Worlds Finest team up through the eyes of an open-minded author like Kevin J. Anderson could be a very fun read. I'm always up for a good Superman/Batman early tag-team tale. Plus, it comes with a nice paper-back cover articulated by the GREAT Alex Ross:
