Superman : Grounded, book 1
Joe Michael Straczynski et G. Willow Wilson2012

In the aftermath of the 100-Minute War—the annihilation of New Krypton and the havoc wreaked on Earth in his absence, Superman find himself an expatriate of two worlds.

The dissent over his abandonment of Earth during the crisis proving too much for some. Superman returns from battle only to discover the people he left behind brimming with vitriol over his desertion. Accusations fly, blame is placed, questions demand answers.

With an entire race destroyed, loved ones lost, and countless lives taken in the onslaught, only one question remains:

What is to be gained from so much loss?

With a weight that is almost too much for the Man of Steel to bear, how does the Man of Tomorrow begin to repair the ruin today? The war may be over, but the journey has only just begun.
