Wasteland
Oni Press.
1 Cities in Dust (1-6; w Antony Johnston; a Christopher Mitten). [From Oni Press: A hundred years after the Big Wet, Earth is broken -- a barren and infertile world where the few survivors struggle for survival. When Michael, a scavenger bearing strange gifts, calls at the shanty town of Providence, the effects are devastating. Now the townsfolk must cross the deadly wasteland to Newbegin, a nearby city where the past meets the new status quo. But Newbegin's cruel dictator is busy oppressing anyone not belonging to his church -- which includes the Providence survivors.] 
2 Shades of God (8-13; w Antony Johnston; a Christopher Mitten). [From Oni Press: The second sensational collection in Antony Johnston and Christopher
Mitten's sci-fi western epic arrives! One hundred years after the
world-changing event known as "the Big Wet" the world is a much changed place. Refugees, political in-fighting, religious persecution, and vicious attacks from savage tribes all are just part of why Comic Book Savant called Wasteland “100% comic goodness!”]
