I was thinking the cover could be a dark creepier forest that looks like it would suck you in and spit out your bones. This is a post-apocalyptic world where the population isn't huge, so the forest is somewhat lush with pine trees, untouched by pollution. Seen over top of the trees in the distance are The Big three (three government tall glass buildings) shimmering (one in the front bolder than the two on either side and slightly behind). The main character would be walking into the forest and looking hesitantly over her shoulder. Harley (WOMAN) (main) has messy brown hair that goes past her shoulders, brown eyes, face slightly bruised.
