I recognize that it's not economically feasible for an Indie writer to commit to such a long book, unless it is conceptually and artistically within the author's vision for such a work to be of that length in the first place.
My point is that I have read works of that length throughout my reading and academic career. (At one time I was working on my Ph.D in English Literature, so I was very cognizant of literary works of that length or greater.)
On the Indie front, however, works of great length seem to be about as plentiful as the Dodo bird and, even when one does exist, it appears to have little (if any) literary reading merit except as a work of curiosity.
But....I love long novels. Indie writers may be the death of literature (which is another topic and/or another thread), but I still long to read a lengthy work by an Indie writer.
I read Indie writers. They have their place in the scheme of things, even though many (or few?) may not be aware of any purpose served except as one which sits couched within the context of a self-serving promotional paradigm.
So......we shall see.
My fingers are crossed for that Indie writer with artistic vision...for that Indie writer with two reams of paper.
