I'll be ordering a few books soon, and this time around I've decided to diversify, so I'm looking forward to some recommendations. I've yet to find a book that didn't pique my interest.... ranging from guilty-pleasure fluff to a cookbook, Shakespeare or the Bible, anything goes.
If you had to name one book as your absolute favourite, which one would you choose? Why?
Edit: Okay, I can't choose just one, so let's make it
three!

I'll list mine later.
