Edinburgh, 2014. Two writer friends, Damaris and Oliver Pablo, escape London, the city that killed his brother. They spend their days trying to get to the library, bickering over their tanking bitcoin, failing to write or resist the sadness. Then they meet Diego, a poet. He tells them he is named for his mother’s island in the Chagos Archipelago, which she and her community were forced to leave by British soldiers in 1973. Damaris and Oliver Pablo become obsessed with this notorious episode and the continuing resistance of the Chagossian people, and want to write in solidarity. But how to share a story that is not theirs to tell? And how to account for a loss not theirs to grieve? A tragicomedy interrogating the powers of literature alongside the crimes of the British government, Diego Garcia is a collaborative fiction that opens up possibilities for the novel and seeks other ways of living together.
