On yesterday’s This Week in WoW blue post, Blizzard announced there would be a new book available for pre-order later this week.
Since then, it has been discovered that Amazon France has a new WoW book listing! This new book is title War of the Scaleborn, and it has a (probably placeholder) release date of October 31st, 2023. Thanks to Mymindwontquiet for the tip!
