I’m looking for the title of a book I read as a kid around 10 years ago, in German (in Germany). The book was already quite old then, hardcover.
It’s about a civilization of little people who live on a single tree, kind of like Terry Prattchett’s Carpet people, just on a tree (also inside the trunk and branches). All I remember about the story is that the protagonist, a boy, is on the run for the most part of it.
I checked and it’s not The Minpins and not the Faraway Tree as there was no mention of any humans and the whole story takes place in the tree. It’s not necessarily a children’s book and it was about 400 pages long.
