Wes asked for some examples of books narrated in deep POV.
I used to know a bunch, when I was writing the POV book. First thing I'd say is-- there are not nearly as many books "in" deep POV as authors who say they write in deep POV. :) And there are many more books that actually use deep POV along with a more distant POV too. Let me see if I can think of some.
Well, Ulysses (by James Joyce) is VERY deep POV, stream of consciousness, at least the Leopold Bloom and Molly Bloom passages. (The Stephen Dedalus passages are more distant.)
Sole Survivor, by Dean R. Koontz. This is almost unbearable, at least the first couple chapters, because it's a third-person narration of a man in terrible grief. If you can bear the vicarious pain, it's a great example of deep POV.
Mr. Murder, also by Dean R. Koontz. You know, really, when Koontz is on, he's the best at this. His deep POV narrators range from a child to a serial (insane) murderer, and then narrative styles reveal a lot about the characters.
Mrs. Dalloway by Virginia Woolf. This is almost stream-of-consciousness.
Horse Heaven by Jane Smiley. This has some really interesting deep POV passages from --get this-- the horse's POV.
Flowers from the Storm, by Laura Kinsale. Again, the deep POV is in certain passages, not the whole book, but she really explores the inner reality of the hero, who is aphasic after a stroke.
Just a start-- can you all give Wes some more suggestions for novels that make good use of deep POV?
