Book excerpt: Some of our strongest, most lasting relationships are hidden in plain view—those we have with objects. What do our possessions do for us? And how do they do it? In The Promise of Things, Ruth Quibell explores what our possessions say about us: who we think we are, what we long for and struggle against. It invites us to think about how we use things, what makes them precious, and why we find it so hard to throw these objects away.
