The plot
It is an apocalyptic period, the world is overrun by robots, and the girl (female main protagonist, but I forgot her name) is struggling to survive. She has the help of a robot that helps bring her food that was with her before the apocalypse.
You can put your consciousness inside the robot in the form of a disk, and 1 robot can't hold more than one consciousness.
The robots don't have emotions but they try to live like humans (doing the everyday things humans did) in order to feel emotions or understand them. The robots have weapons blocking her path to wherever she wants to go.
Later she ends up getting captured by the robots and is forced to work alongside others. Later the others find out her identity, and because she's good with robots because of her father she's sent to treat the leader of all the robots which actually turns out to be human. However, the person has a broken consciousness or a bad link. As she pretends to be fixing the leader (the main villain) instead of fixing him she implants a different disk in his body that helps solve the apocalypse or crisis.
The girl's dad used to be the greatest robot maker of her time. And at one point the girl got really sick, however she thought she got better. But it turns out she died and actually her consciousness was actually transferred to the robot. She's the only robot capable of feeling pain and emotions.
She doesn't know that, though, and as the novel ends her robot companion puts her hand in the fire saying "stop thinking about it and you won't feel the pain anymore". At a point the pain gets scorching hot, however slowly it dies away and you can see metal behind the burnt skin, making her realise that she's actually a robot.
