Islands are everything. Each of us lives on an island, and moves between them constantly. Your island might be called London, or Northumberland, or Withington. Or it might called the office, the supermarket, the bus. For a little while, your island might be as big as a cinema screen, and the population is the audience around you. Sometimes, it’s an island of three – my wife, and my daughter and me, drinking tea by the stove. Sometimes it’s an island of one, contained within the covers of a book. You know the shores of your island entirely, and you look beyond them often. All of life is an archipelago.
