Of all the great novelists writing today, none shows the same gift as Martin Amis for writing non-fiction - his essays, literary criticism and journalism are justly acclaimed. The Rub of Time comprises superb critical pieces on Amis's heroes Nabokov, Bellow and Larkin to brilliantly funny ruminations on sport, Las Vegas, John Travolta and the pornography industry. The collection includes his essay on Princess Diana and a tribute to his great friend Christopher Hitchens, but at the centre of the book, perhaps inevitably, are essays on politics, and in particular the American election campaigns of 2012 and 2016.One of the very few consolations of Donald Trump's rise to power is that Martin Amis is there to write about him.
