From the title page:
"An original retelling"
So... a complete fabrication? Nothing at all to do with the original?
Is it ever "a word-for-word retelling of the original"?
Cataloguing may seem a dull and dry task to many people, but I spend most of my day in silent dialogue with authors and publishers, quietly chuckling to myself at flowery praise and implausible plots, or muttering under my breath at the librarian who chose to purchase such a book.
Just the sort of thing I enjoy.
