Here you can read an online science fiction novel (in German). The novel has been written by Martin Schellmoser and Maximilian Lückenhaus. Martin Schellmoser also had the original idea of writing the story as a "jam session" with both authors alternatively writing one chapter after another. At this, there was no master plan for the story and no arrangement between the two authors while improvisationally writing their chapters. Both did not know how the other one will continue the story. Unfortunately, this experiment of literature is currently only available in German (sorry).
