Between 1930 and 1935, William Faulkner came into full possession of the genius and creativity that made him America’s greatest writer of the twentieth century. “As I Lay Dying” is a dark comedy, full of horror and compassion, of a rural Mississippi family bearing the corpse of their matriarch to burial in town. “Sanctuary,” a violent novel of sex and social class that moves from Mississippi back roads to the flesh-pots of Memphis, features a sadistic gangster named Popeye and a debutante with an affinity for evil. “Light in August,” a near-religious vision of the hopeful stubbornness of ordinary life, is perhaps Faulkner’s most moving work. “Pylon,” a tale of barnstorming aviators, examines the bonds of loyalty and desire among three men and a woman. All are presented in restored texts as part of The Library of America’s new, authoritative edition of Faulker’s complete works.
