Der Lange Kosmos

2070-71: Decades after the discovery of the Changer, which made it possible for the first time to commute between parallel worlds, a new posthuman society flourishes on Long Earth. But it is thrown into turmoil when a mysterious message arrives from the middle of the galaxy. In it, the super-intelligent Next discover the blueprints for an artificial intelligence of massive proportions. Once built, the computer could not only change the position of Long Earth in the cosmos forever, but also answer the question of the meaning of life. But no one knows the sender of the message, and no one knows if its intentions are peaceful.
