The Sewer Rat is a deeply curious and independent woman, tomboy, accustomed to surviving on her own in a post-apocalyptic world. She is brave and determined, yet she also has a tender side that occasionally surfaces, especially in the presence of a civilian, a young man. The Sewer Rat hasn't really talked with boys before, so she has to learn to trust and communicate in a new way with this young man as they try to make their way together in this harsh world's new reality.
