Professor H. Hrush was the author of a book entitled The Lost Twenty: Dooku's Rise, though it was published without consent from the proper parties. The book concerned a Jedi Master named Dooku, who resigned from the Jedi Order to found a militarized confederacy of worlds that wished to secede from the Galactic Republic. For a time, Hrush's book was listed as the number-two best-selling book on a list compiled by HoloNet News in 23 BBY.
