The new book by the author of Capital is a dystopian thriller set in a near-future Britain that invites comparison with Atwood’s The Handmaid’s Tale and Orwell’s 1984. Kavanagh begins his life patrolling the Wall. If he’s lucky, if nothing goes wrong, he only has two years of this, 729 more nights. But somewhere, in the dark cave of his mind, he thinks: wouldn’t it be interesting if something did happen, if they came, if you had to fight for your life?
