The Office of Letters and Light chose 30 participant authors to receive covers by a group of talented designers curated by John Gall. Each designer received a title and plot synopsis for a planned National Novel Writing Month novel (or novel-in-progress). Each designer had just 24 hours to create a book cover to accompany the title. These book cover designs, along with a synopsis, were then posted on the The Office of Letters and Light blog each day for the 30 days of November. A project entitled 30 Covers, 30 days.
