I am not a big reader, but my favourite book is not even 200 pages, is from the 19th century it features theme of patriotism and political disillusionment that can still reasonate with people here, a character that tries to make up his growing disillusion in living in freedom as he witness his country being politically and graphically dismembered he seeks confort within nature and people but over the course of the story he find himself at odds with what seem an inevitable destiny, an impossible love, an uncaring society that is too caught up in its own traditions, the pain of living as an intellectual that has been shown through enlightment a vision of what society could be and find himself alone, toward the end even at odds with Nature itself which now appear dangerous and malicious, (one of the many recurring themes in his poetics).
Is called the last letters of Jacopo Ortis, the book I got puts it all in just 135 pages.
Also another quick comparison Lord of the Rings, the trilogy I got is around 1K pages I think, I would have to go and find it to be sure.
What is the writer doing to pad out such a small story?
