Writing a novel requires the creation of a living, breathing, fully populated world. Deities can pull off a trick like that in six days, but how long should it take to write a book?
William Faulkner wrote Light in August in seven months, a slog compared to As I Lay Dying, which he wrote in less than six weeks while working the night shift at a power plant. Jack Kerouac spent seven years on the road, but the actual writing of that iconic book took less than a month, typed on a single, taped-together roll of paper. Anthony Burgess wrote A Clockwork Orange for money and churned it out in three weeks. John Boyne gave voice to The Boy in the Striped Pajamas in a breathless two and a half days.
