Bad

The word that is hidden in the underneath book is bad. This was in an Oxfam bookshop window. The full title is " Slightly Bad Girls of the Bible."
Really, who would ever buy such a thing, Slightly Bad? It is the Bible after all.
Who would publish such a book, and why?
It poses more questions than there are answers methinks. Just like religion in general.
Is it trying to be modern and racy? Having a laugh surely.
