We love books. We take them to bed with us. They weigh down our suitcases when we go on holiday. We display them on our bookshelves or store them in our attics. We give them as gifts. We write our names in them. We take them for granted. And all the time, our books are leading a double life.; The Secret Life of Books is about everything that isn't just the words. It's about how books transform us as individuals.
