Neither of those books were "odd", IMO.
However, a book that was odd was Catcher in the Rye. When I finished it (a long time ago) I had no idea what I had just read. I later assumed it to be "four days in the life of a handicapped kid", and it was a classic because the author did a good job of viewing life through a handicapped kid's eyes. Even later, I look it up on wikipedia and apparently I'm the only one that thought the kid was handicapped.
