Why are books so very powerful? What do the books we've read over our lives - our own personal libraries - make of us? What does the unravelling of our tradition of public libraries, so hard-won but now in jeopardy, say about us? The stories in Ali Smith's new collection are about what we do with books and what they do with us: how they travel with us; how they shock us, change us, challenge us, banish time while making us older, wiser and ageless all at once; how they remind us to pay attention to the world we make.
