This is a story I absolutely wanted to do even before I had half-read the first book. This is such a captivating story it's incredible.
I have also never worked this long on any other story expect those of Andur. The reason being that Until Death? was the first ebook I did, and so I didn't had any tools, nor I knew them.
For Once a Hero... When I tried to use them, my script crashed at the tenth chapter... Mean I had to do it manually then. (Also mean I have to work again on my tools).
It also mean that Once a Hero isn't a simple story, it's a complex one, thought thoroughly with a complex writing. To display it, you'll have to have a good application. By example I know a lot of you use Moon+Reader (I did too), if you ever try to read with (this shit), well, it will be near impossible. You won't understand what's happening.
I strongly advise my visitors to check on the FAQ, I added a section to test your epub reader, if it fail, just check the other section giving links to good epub readers.
Else, just take the PDF hey... It's less cooler, but less work too.
