A book by E.M. Forster
This book was first published in June 1924. Forster himself was in his early fourties when he finished writing it. He was an experienced traveller and visited India at least twice.
For non native english speakers, this is not an easy book to read with lots of specific words and terms. But it still is a great read when you don’t mind putting a bit of work into it.
Even for native english speakers, it is not necessarily easy to read. So you might have to look up some of the terms mentioned anyways.
Once you are reading though, the suspension is catchin. You might discover a whole new world.
