Looking for good book suggestions

I'm going on vacation soon and need something for the plane. Anything goes - fiction (historical or otherwise), poetry, nonfiction, science fiction, graphic novels, mysteries, you name it, I'll give it a shot as long as it's quality. I'm looking for entertaining books, change-your-life books, and books that challenge your thinking.

I can swim through pages like a fish through water so length is not a barrier (although I'd rather not bring Infinite Jest in my carryon.)
