A recent book that I doubt many have heard of, but which is both well written and provocative (its underlying themes include the notion that consciousness is an impediment to intelligence) is Blindsight by Peter Watts.. being SF may limit its appeal, altho well-written SF has literary merit imo.
And the enormous work (The Baroque Cycle) by Neal Stephenson is nothing short of brilliant in my view, but at more than 2700 pages (originally published as 3 hardcover books, but clearly a single work). It's a book I look forward to re-reading eventually.... but it may be tooooo much for any book club for sloths..
And Alex may not want to identify with the main protagonist... who has had an unfortunate injury to a certain, very important, part of his anatomy quite early in the saga. He otherwise meets most of Alex's criteria!
