Has anyone had an author converse with their book club?

At the end of her book, The Nightingale, Kristin Hannah talks about her support for book clubs, and says to reach out to her if you’d like to have her speak with your book club over speaker.

I think this would enhance the book club experience so much to be able to speak with the author and ask questions.

This is the only time I’ve seen this at the end of a book. Anyone see this elsewhere or something similar?

Has anyone done this? What was the experience like and what did you talk about?
