Die Gezeitenwelt (World of Tides[1]) is the name of a series of German fantasy novels.
They are set on a planet named World of Tides that is hit by large fragments of a comet with dramatic consequences: The coasts are hit by gigantic tsunamis, earthquakes alter the landscape, a global climate change ensues - and mysterious magic awakes, that lets monsters appear and dreams become reality.
A distinct feature of the Gezeitenwelt is its attempted realism in a fantastic context, which is based on research by the authors with the help of geophysicists, archaeologists, anthropologists and biologists.
After the release of the introductory group, the publisher Piper Verlag offered only to finish the series with one instead of eight more books, which the authors refused.
The maps of the world were designed by Franz Vohwinkel, who became known for his illustrations of games like Settlers of Catan and Magic: The Gathering.
