Diana Gabaldon is nearly finished with the next book in her megapopular Outlanderseries, Town and Country reports.

The author updated fans on the status of the ninth book in the series, Go Tell the Bees That I Am Gone, in a hashtag-heavy tweet:

The series began in 1991 with the novel Outlander, about a 20th-century woman who time-travels to 18th-century Scotland, where she falls for a Highland warrior. Seven more books have followed, most recently Written in My Own Heart’s Blood in 2014.

The series spawned a hit television show, Outlander, which premiered in 2014 on the Starz network.

Fans have been clamoring for the next installment in the series for years. The main page of Gabaldon’s website reflects the questions the author gets about the book, with a paragraph reading, “After I have finished writing BEES, a lot of further work has to be done (by my publishers and I) before BEES will be on the bookshelves for you to buy, such as editing, typesetting, creation of a cover, etc. The publishers will determine the final release date.”

Go Tell the Bees That I Am Gone won’t be the final book in the Outlander series. In a tweet from late 2018, Gabaldon wrote that “Book 10 will be along summat later.”
