I didn't downvote, but it did take me only a couple of Wikipedia clicks to bring up the article on Neapolitan Novels (https://en.wikipedia.org/wiki/Neapolitan_Novels). Per the article "the series has sold 10 million copies in 40 countries".

It also apparently had enough clout to get an HBO / RAI TV series produced out of it, which will possibly up the recognition factor for her name and her works considerably depending on the success.

This is not super super stardom level (the top living novelists have sold half a billion novels -- https://en.wikipedia.org/wiki/List_of_best-selling_fiction_a...) but that's still an impressive number, I would say it is within the top tier.

(A fun comparison to another HBO show: When Game of Thrones started, A Song of Ice and Fire had sold 15 million copies worldwide -- https://en.wikipedia.org/w/index.php?title=A_Song_of_Ice_and... . In a similar ballpark, in other words.)
