Okay, chapter three (of Fallout Equestria: Letters to Celestia) has been split into chapter three and partial chapter four. The chapter three part has now been reworked by me, to be self inclusive as a chapter, so it doesn't feel disjointed, and has now been sent off to my editor (or will be when he nips online).
I shall then work on chapter four, and when that is finally done, I will be moving on. The next book after chapter four is the second book in Knights of Little Canterlot. After that, likely another two FoE chapters, then it's back to Daring Do books, and between each book, I'll probably shove our two FoE chapters. That way, despite working on commission books and personal projects, this large tale wont be forgotten, or left to rot, and will still get 'fairly' regular updates. ^-^
