It's that simple! I only send announcements about new releases, and I never sell or share your email address with anyone else at all. (I never did, even before the EU law changes. Lots of writers share them with Facebook. I never trusted FB as far as I could throw Zuck's vast team of lawyers!)
You can also sign up at Bookbub or via Amazon's +follow function (though Amazon's doesn't always work.)
Thank you for reading.
