I have now uploaded cleaned up and edited EPUB and MOBI files to Bookapy of A True History Book One. They have been checked with Sigil and Calibre and should work. I specifically took each HTML file and made it an individual chapter, and created the TOC as well.
Please let me know if you have issues with them. My understanding is that if you purchased the book, you can download the file again even after I've changed it. I just write the stuff, not run the website that hosts them. Thank you.
