Warning! Some spoliers abound!.....
It will be two volumes. I just bought the 1st volume at a local bookstore.
What I loved is how it captured the can-do American attitude of that time period that so often is perceived to be arrogance, because so often it is a form of hubris -- we'd just won a world war, we bad the bomb, and "American know-how" so why do we need "Freaks" when American mortals can do it themselves? Yet, the "mortal" heroes and teams are hardly normal. The Loosers, the Challengers of the Unknown, the X/Suicide Squad would all make for great M&M adventuring and show that even pl 5 has great story potential.
Also, the scenes with the Martian Manhunter transforming into bugs bunny -- priceless.
Wonder Woman empowering the village women, very well done and seemed true to the character.
What really intriuged me was the take on John Henry. And Hal Jordan, clearly the focal character, and a pacifist. hrmm -- again a nice example of a character "flaw" that gives a lot of ingame play potential.
And John Johns is just screaming for a writeup via Noir
Cannot wait to read the 2nd trade paperback.
