Harper Lee remains a landmark figure in the American canon – thanks to Scout, Jem, Atticus, and the other indelible characters in her Pulitzer-winning debut, ‘To Kill a Mockingbird’, as well as for the darker, late-’50s version of small-town Alabama that emerged in ‘Go Set a Watchman’, her only other novel, published in 2015 after its rediscovery. ‘The Land of Sweet Forever’ combines Lee’s early short fiction and later nonfiction in a volume offering an unprecedented look at the development of her inimitable voice.
