"She did not remember the wild dog attack that nearly killed her thirteen years ago but the scars were a constant reminder of how dangerous the wastes were for a child."
I think this might read better with the word "had" between that and nearly killed, i.e. "She did not remember the wild dog attack that had nearly killed her thirteen years ago, but the scars were a constant reminder of how dangerous the wastes were for a child."
“Ms. Eva, are you okay?” the robotic voice of Jill came from a few feet away where Eva’s father was repairing her. “You seem troubled.”
Didn't have a problem with this paragraph, just thought I'd point out that, if you're going to be using the word robot frequently throughout this piece, it might be preferable to use a different adjective than "robotic" here, maybe metallic or somesuch. I think the fact that Jill's identified as a robot quickly enough in the next paragraph would make it OK to make the change, if you chose to do so.
Random musing: Could capitalize "Wastes" if they're an important enough setting in the piece, or give them a spiffy name.
I think the breast-to-naval scar from the feral dog attack could probably be explained with just a little creativity, if you were so inclined. Wasn't a problem for me, but Bent Tree's obviously had a little more experience than I have, so I'd defer to him on this matter and add some further explanation.
I agree that the line about the robots and cyborgs having their skin removed is a great hook. I'd love to see it depicted graphically. If you're into gore, that is. The dangerous wastes are pretty damn intriguing, too.
Anyways, hopefully you'll find something in my ramblings to help you out or inspire you. Keep up the good work.
