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