“There’s an irony to the title of Roddy Doyle’s 11th novel, in that the book eschews most of his trademark humour and the laughs fall thin on the ground. His darkest and perhaps finest work since The Woman Who Walked Into Doors 20 years ago, Smile combines tropes from the various strands of Doyle’s career—childhood memories from the Barrytown trilogy, middle-aged regrets from The Guts and Bullfighting, pub conversations from Two Pints—and merges them into a unique novel, one that is terribly moving and even, at times, distressing, while saving its greatest surprise until the end … While Doyle has never been a particularly experimental writer, he takes great risks with his story as the novel progresses. To say more would be to spoil the truly unexpected climax that Smile reaches, but suffice to say that to call this the least Roddyesque of Doyle’s work would be an understatement. There is a brave and complex ending to the novel, one that will leave readers astonished.”
