Ah! Finally I found the original language version of a book, I liked as a child: The Magic City
I didn't remember the title or author, so it was hard to search for it. More so, as I only read the German translation.
I knew, I read books by Edith Nesbit, so I looked at your listing. And the first try showed me the correct one. I recognized it by the drawings. Thanks a lot for providing this.
Only downside: No PDF version. When I've got time™, I'll probably will build one. 😄
