I know nothing about the Orthodox Jewish faith or rituals, so the descriptions of this lifestyle were completely new to me, but this was a very interesting read. Quite the journey for both the hero and heroine. I don't know about the BDSM aspect of the story. It didn't bother me, but it didn't do much for me, either. (I was pleased that there was not an infamous club with other masters and sharing of subs, etc. - so not in to that.) I was more interested in the development of their relationship.
This was free and I'm very happy I picked it up.
