(NewsNation) — Sarah Ferguson, the former wife of Prince Andrew, was set to publish a children’s book, but the already delayed “Flora and Fern: Kindness Along The Way” has been withdrawn, according to analytics firm Nielsen.

The book was initially slated for release on Oct. 9 and then Nov. 20, but it has since been removed from online listings.

Nielson confirmed to the BBC that the book has been “withdrawn from sale” at the request of the publisher, New Frontier Publishing.

The former Duchess of York has published more than 50 books.

The 66-year-old lost her royal title when her ex-husband gave up his title over ties to the late convicted sex offender Jeffrey Epstein.

The former prince, now Andrew Mountbatten Windsor, was named in email exchanges from Epstein, which the United States House of Representatives revealed last week.

In September, several charities dropped her affiliation after a 2011 email was leaked, revealing that she called Epstein a “steadfast, generous and supreme friend to me and my family.”

It’s unclear why the book was withdrawn from sale.
