For your perfect summer read I’d recommend Zoé Oldenbourg’s 1949 classic medieval adventure The World Is Not Enough. It’ll comfortably occupy you for a good fortnight and while it’s thrilling, romantic and heartbreaking enough to keep you turning the pages, it’s also so beautifully written and historically illuminating that you won’t feel the emptiness and self-disgust you do when you’ve finally got to the end of a bog-standard airport thriller.
