Heidi, a girl born in garbage. Rex, a soldier gone rogue. The only thing between them and their destiny is an empire of a hundred different Earths, across a hundred alternate timelines. One majestic planet dominates them all: HIGHER EARTH
In the debut issue, written by Sam Humphries and illustrated by Francesco Biagini, Rex--unidentified throughout the story--arrives from one of many divergent Earths to find Heidi, but things are not as they seem and he is not the only one looking for her. Things are further complicated by the fact Heidi does not recognize him. After Heidi's home is destroyed and a confrontation with an unknown attacker promises danger, Rex has no other choice but to save her by taking her to the Higher Earth.
Variant covers available, each sporting a $1 cover price.
