In the novel humanity has gone sterile, like the youngest people alive were teenagers. There’s this teen that I think fishes an old hospital bracelet out of a river and it belonged to this sickly girl from many years prior who was terminally ill. The story goes that the girl’s family was super rich and paid to have a clone of their daughter so they could harvest the clone’s organs to save her, but then the daughter befriends the clone and they run away together. They live in the sewers for awhile eating I think cat food, and eventually the daughter dies from her illnesses. The clone turns out to be the old grandma like character and from her they figure out how to clone other people, and humanity survives through cloned teenagers.
