Would you buy a beautiful/upgraded version of a book you already love, or risk 'wasting' it on a book you don't know you'll enjoy?
I received a Waterstones voucher for Christmas and I'm really reluctant to spend it on something I don't know I'll love.
I know this might sound ridiculous to some but I'm trying to cut back on spending at the minute so want to use it carefully.
Can anyone recommend any impossible-not-to-love book store purchases?
