It’s taken a while, but a new version of the Fool on the Hill ebook, free of the many typos that plagued the original edition, is now online. If you’ve previously purchased the ebook, you should be able to update or redownload it without charge, though the exact mechanism will vary depending on whether you bought it for iBooks, Kindle, or some other platform.
A quick way to confirm that you’ve got the new edition is to look at the List of Major Characters at the beginning of the novel. Preacher should be identified as the “Bohemian Minister of Ministry”—the uncorrected text said “Bohemian Ministry of Ministry.”
The new print edition is now in stores as well. Just look for the yellow cover.
