More than a century after his death, Mark Twain’s publishing life continues.

Doubleday Books for Young Readers says it has acquired a fairy tale only recently discovered – titled The Purloining of Prince Oleomargarine.

The work is based on 16 pages of notes written by Twain in 1879 – that were spotted at the Mark Twain Papers Project – at the University of California at Berkeley.

The unfinished story has been expanded to an 11-chapter, 152-page illustrated book to be published in September.

The Purloining of Prince Oleomargarine is the story of a boy who can talk to animals – and their joint effort to rescue a prince.
