One of my publishers has just informed me about a new social media site geared specifically to authors and their readers, giving them all a chance to interact and share their thoughts on an author's books. https://www.wavecloud.com. The site also sells e books.
It's easy and free to join, and if you join now you can download a free e book of your choice from tens of thousands of offerings. My book, An Imperfect Miracle, is available for download on the site, and you can find it at Wave Cloud.
