... on Facebook, twitter & Pinterest for sure! 

How to do that? - very easily:

- Click on your book you want to share to open it as if you were about to read - then look at the Right Side of the Screen, you'll see the letters & symbol 'f' , '🐦' & 'P' - which mean 'Facebook', 'twitter', 'Pinterest'...

- so if you want to share the link to your book on Any of those Social Media - just click the Letter or Symbol of it, the link Sending Space will open - & you can share Your Book!  ^_^

Adding some info to it - ot just clicking 'Send'
