A story by Mark Twain that was only recently discovered will be published later this year. The AP reports that the book, “The Purloining of Prince Oleomargarine,” is scheduled to be released Sept. 26.

The new story, described as a fairy tale, will be published by Doubleday Books for Young Readers.

“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 story reports. “The prize-winning team of Philip Stead and Erin Stead have expanded the unfinished story to an 11-chapter, 152-page illustrated book. The Steads are best known for ‘A Sick Day for Amos McGee.'”

“The Purloining of Prince Oleomargarine” focuses on a boy who has the ability to talk to animals and joins forces with them to rescue a prince.

Born Samuel Langhorne Clemens, Twain, a writer, humorist, entrepreneur, publisher and lecturer, died in 1910.
