With Zamonia Walter Moers invented a world like Terry Pratchett did with his Discworld and populated it with different people and characters. Now we are introduced to a new character - Optimus Yarnspinner - who is going to investigate the mystery of a short story and his unknown author. His quest leads him to the City of Dreaming Books and that's where the adventure begins to start in earnest.
It's absolutely amazing and wonderful how the author uses language to describe every event and scene.
The newspaper "Die Welt" has called it a love declaration for literature, and in that, the critic was quite correct. If you love books and adventures, you should read this book by all means.
