This edition duplicates the text of the North American High Wizardry editions from the 1st ed. hardcover through to the Houghton Mifflin Harcourt mass-market and digest edition paperbacks. Please note that this is not the revised / expanded “Author’s Cut” edition: that will be coming out later in the year.
The International Editions are for readers outside the US and Canada only, so please don’t bother trying to buy a copy if your address is in North America. If you’re in the US or Canada and you want a copy of the High Wizardry ebook, please use this link for the Kindle / .mobi version and this link for the .ePub.
