Originally published as Der Kartoffelkönig in 2013 by Verlagshaus Jacoby and Stuart.

"Once upon a time there was a Prussian King, Frederick, also known as Fritz, who saw potential in the lowly potato -- a newly introduced crop from South America -- and decided to plant it for his people. However, it quickly became clear that his subjects didn’t like being told what to eat. Determined to see the potato thrive, Fritz cleverly used reverse psychology to pique his people’s curiosity and make the crop popular, and the potato has flourished ever since. The book includes a short informational note on the historical background to the story" --From publisher's description.
