Katyusha is a young girl who has dealt with a lot, her parents died and she lost all of her limbs before getting them robotic. She was within the Witwicky family, where she had a new brother, Sam Witwicky, who damn near drives her mad. Eventually, they get caught up in an alien war because Sam's car was actually an alien. Katyusha also has been going in and out of consciousness, seeing things of the past, present, and future in front of her. She will learn things about herself and the secret behind why both sides seem keen on keeping her alive.
