Wretches #1

"Alone on the tough streets of an alien city, far from the lifeless planet they once called home, siblings Shea and Sean spent their youth struggling to survive. Still suffering emotionally from the loss of everything they'd ever known and loved, Shea and Sean have nothing else in the universe but each other. Forever outrunning the horrors of their past, they survive the only way they know how- by hunting and killing sentient robots for profit! Now, when the rough path that they had no chance to follow finally catches up to them, will they be able to keep each other safe or will they lose the only important thing they have left, each other?"
