Juneteenth, by Ralph EllisonRead about another entry on the list.
Much like David Foster Wallace, Ellison spent more than a decade trying to figure out how to follow his watershed debut Invisible Man. Even after 40 years, he never figured it out, and left behind some 2,000 manuscript pages upon his death in 1994. Five years later, a much-elided version was released as Juneteenth, including roughly a quarter of all available material. More than a decade later, the complete work-in-progress was published as the 1,100-page Three Days Before the Shooting, providing a fascinating study for lit fans with a lot of time on their hands.
