Still, hoping to find something within the genre that is new and hopefully interesting, I come across something that currently proliferates in the self-publishing circuit: spanking romances. My blog linking function is not working (I don't know what Bravenet is doing nowadays), so I will just paste a few product URLs here as examples:
http://www.lulu.com/content/1137418 (I bought this one)
http://www.lulu.com/content/436340 (Holiday Spanking Stories - what on earth?)
I even found a few inspirational spanking romances, which I dared not buy, about wives discovering the new meaning behind God's decree to good pious Christian women to "submit to God by submitting to your husband". Are those books aimed at some kind of niche audience with a kink for spanking and Bibles or are they really serious about the whole spanking of wives being part of virtuous Christian living? I will let some other people find out.
I'm going to read now. Wish me luck!
