“Less” won the Pulitzer Prize for fiction last week and was a surprising choice because few comic novels have won the prestigious award. The judges’ citation describes it as “a generous book, musical in its prose and expansive in its structure and range, about growing older and the essential nature of love.” The book follows Arthur Less, a failed novelist about to turn 50. When he receives a wedding invitation from his boyfriend of nine years ago, he decides instead to run away from his problems by attending a few half-baked literary events around the world. He will almost fall in love in Paris, almost fall to his death in Berlin, barely escape to a Moroccan ski chalet from a Saharan sandstorm, accidentally book himself in as a writer-in-residence at a Christian retreat center in Southern India, and have a chance encounter on a desert island in the Arabian Sea. Andrew Sean Greer began this comic masterpiece as a very serious novel about being gay and aging. “But after a year, I just couldn’t do it,” he told The Washington Post. “It sounds strange but what I was writing about was so sad to me that I thought the only way to write about this was to make it a funny story.”
