Every year since 2014, the Scottish artist Katie Paterson – along with her Norwegian counterpart Anne Beate Hovind and a group of trustees – has invited a prominent writer to submit a manuscript, and the commissioning will continue until 2113. Then, a century after the project began, they will all finally be published…”
