You try every trick in the book to keep her. You write her letters. You drive her to work. You quote Neruda [. . .] You try it all, but one day she will simply sit up in bed and say, No more. In Yunior, a Dominican-American writer and Harvard professor, Junot Diaz has created an irresistibly erratic protagonist, who sweeps you up in the poetic energy of his speech as he rehearses a broad repertoire of bad behaviour. Originally the climactic tale in the chain-linked This is How You Lose Her, 'The Cheater's Guide to Love' is a superb standalone song of decadence and experience.
