Heaven's Ladder (Oversized Softcover)

When the Earth is suddenly stolen from its orbit and transported into a massive alien craft, the Justice League quickly begins an investigation to discover the identity of the culprit and his scheme. Earth's greatest heroes learn that an eons-old race of scientists on the verge of extinction have acquired a plethora of planets in the hopes of creating a world for them to exist in once they have died. Realising that these aliens consider the planets that they are manipulating as insignificant, Superman, Batman, Wonder Woman, Aquaman, Flash, and the Atom must find a way to save the many different worlds while aiding the godlike race in their quest for an afterlife.
