Yes! Very excited for a new book and the series at the same time. If you fb or twitter at all - the author posts Daily Lines - little snippets from the new book, as well as other novellas, pretty much every day.
There are little novellas out there, too, that explain some of the backstories going on. Like this one: DianaGabaldon.com | A Plague of Zombies
And the "Custom of the Army". Wasn't the best of hers, but it was a very quick read as an ebook.
And all the Lord John novels and novellas. And a comic book! - er, graphic novel And the Companion!
