Hey there!
Due to contractual reasons, I need to take down all but 10% of Book 4 from this site and Patreon, as I've done with previous volumes. The full, edited and refined version of Book 4 is up on Amazon, available for ebook and audiobook preorder now (9/14) and will be fully available in ebook, Kindle Unlimited, and Audible formats on September 28th!
Book 5 starts with Chapter 242!
Thank you!
