The engrossing reference book The Legend of Zelda: Hyrule Historia will be available in digital format next month. You will be able to purchase it from the Apple Books store, Amazon and Google Play on 14th April and will be available for $19.99. The Legend of Zelda: Hyrule Historia is 280 pages and produced by Eiji Aonuma and Akira Himekawa. It is currently only available as a $39.99 physical release
There was also a digital release of it on the Wii U, but I think it came exclusively with the Wind Waker Wii U deluxe bundle
The book is about a decade old now. How about new one that includes information on Zelda games made after Skyward Sword?
