Long story short, this book is set in a distopian city the main character a small girl i think she is poor and lonely. She meets a creature that looks slightly like a man but is actually a creature made up of thoasands of insects. The creature is kind and i think he kind of protects her, eventually he takes her to an abandoned underground train station.
That is all i can remember but if anyone knows the book im am trying to recall/find i would be etternally grateful
