What are your favorite books?

I'd love to hear what some of your favorite books are, no matter the genre. They say that to be a good writer, you have to be a good reader and I really need to up my game. I've read mostly mainstream fiction like the Harry Potter books, Hunger Games, His Dark Materials Trilogy, The Lord of the Rings, Ender's Game, Ender's Shadow and a few more in that vein. I've also read more classic fiction like Brave New WorldFrankenstein, etc. I'd like to expand into short story collections as well. I've recently read Stephen King's On Writing and Anne Lamott's Bird by Bird, both writing books. And both are wonderful, down to Earth, and approachable. I highly recommend them for beginning writers. They are encouraging without being patronizing.

So what do you, dear readers, like to read yourselves?
