My books are free to download (but there's a donation button, and some people use it, and I'm very pleased when they do).
If you'd like a different format to convert from, I can provide .odt or .rtf.
If you're really good with epub and can clean up my pitiful efforts, I'll probably be willing to pay you actual money to do that: please mail me!
