And being a relatively slow reader, it felt REALLY good to kill the thing in one setting. I can count on two fingers the number of books I've done that with.
Have you tried anything by John Steinbeck? Both "Mice and Men" and "The Pearl" are very easy books to read. You can knock those out in an afternoon on the back porch no problem at all.
I don't remember anything about them, but I remember reading some Kurt Vonnegut books that my dad had when I was in high school. I remember those being easy to read as well.
