John Carter the End

"Centuries have passed and time has taken its toll on Mars. Conflict burns across the landscape. A war of supremacy and genocide at the hands of a burtal despot has brought the planet to the edge of collapse. A search party has finally located an aged John Carter and Dejah Thoris, living in quiet seclusion on a desert moon, in perpetual mourning for their lost son. How could they be Mars' last hope? Introducing a John Carter story like you've never seen before, from co-writers Brian Wood (Star Wars, DMZ, Northlanders) and Alex Cox (Adventure Time), joined by artist Hayden Sherman (Civil War II: Kingpin)."
