The fourth Diablo 3 novelisation, Diablo: Storm of Light will be released next year, Blizzard announced today. This new novel will bridge the gap between Diablo 3 and its Reaper of Souls expansion next year.
It’s being written by the author of the previous Diablo 3 novel author: Nate Kenyon and focused on the adventures of Shanar and Jacob, who seem to the the Diablo characters de jure right now.
Storm of Light apparently focuses on the nature of being a Horadrim and the cost of putting others’ lives before you own.
You can preorder the book from this kind of sparse, almost shady looking page right now if you care to.
