So if you've already visited the new https://www.sennadar.com site, you've already seen all these covers, but I'll post them here anyway. There are also ebooks available in epub and pdf format, with these covers and the final covers previously posted on here, for download on the site. So if you're looking for the ebooks, that's where they are.
I may in the future create more subjugation covers for each book, but until I have one for every book, I'll just use the same image for them all. Right now, I just dont have the inspiration for that.
