Mark Twain's unfinished children's "book" is now finished.

To say Mark Twain has an "unfinished" children's book soon to be published is a bit fast and loose with the facts.

Doubleday Books, an imprint of Penguin Random House, plans to release the lighthearted Twain fare on September 26, 2017, after author Philip Stead and illustrator Erin Stead worked to complete the book.

According to Doubleday, the story--The Purloining of Prince Oleomargarine--"follows a young boy who eats the flower sprouted by a magical seed and gains the ability to talk to animals. From there, the boy and his new animal friends go off on a wild adventure to rescue a kidnapped prince."

So, it's like Jack and the Beanstalk meets Doctor Doolittle.

In 1879, while the family was visiting Paris, Twain apparently told his daughters a bedtime story following the plot of Prince Oleomargarine. Afterward, Twain wrote 16-pages of notes on a potential full-length book, but left it at that. For over 130-years, the notes remained lost until scholar John Bird discovered them at the Mark Twain Papers & Project at the University of California at Berkeley in 2011.

Somehow, 16-pages of Twain's notes evolved into a 152-page storybook with illustrations by two other people.

Notes = 152-page book.

A "Twain" book.

Notes.

Based on this metric, I have written tens of thousands of books. It's impressive, if I do say so.
