Do you really want a random book?
Of course you do. You may not know it, but you do. You will be elated and disappointed in equal measure. That’s the point.
And even if you don’t want the book, you can give it to someone you don’t like.
You can experience the joy of opening a Christmas present from an aged aunt who is determined to divest herself of her enormous library. From Austen to Zola, you will never know what to expect.
