Books with fantastic endings

After a quick break I'm back on the Long and Short Reviews topics, and this one intrigued me. I can think of plenty of books with endings I liked, but not many of them were fantastic.

I ended up with just one. "The Beguiled".

"The Beguiled" is a book which suffered a lot when the film was made, as not only did it seem to be written from bullet points while missing all the character development, but the trailer gave away the ending. Which is a shame, because I genuinely didn't see it coming.

Spoiler alert for those of you who haven't read the book or seen the trailer...

The women and girls are housing an injured soldier in a school, and gradually coming to realise that he's doing them more harm than good by manipulating them all. So how can they get rid of him?

Well, one of the girls happens to know where some poisonous mushrooms grow...

So which books did you think had fantastic endings?
