As a student of the Song of Songs, I've read many books about it. But I've never read a fictional account of King Solomon's relationship with the Shulamite, until now.
Mesu Andrews' well-researched book Love's Sacred Song delves into the culture of the time while exploring the history around the Song of Solomon. I don't often recommend books on this blog. (I save that for my book review blog where you'll find my review of this book.) But this time, I couldn't help it. Understandably, it's fiction, but if you're interested in learning about what might have happened, and learning more about the culture of the day, I'd recommend checking out Mesu's book.
I'm including the links below (print and e-book, in that order) in case you want to check it out.
