Where to promote your book? Anywhere that is allowed for you to promote. I say go ahead. I promote my book Living this thing called Life on social media.
Facebook- I am a part of nearly 40+ Facebook groups. I promote when I can and have time too. I promote the picture and Amazon book link.
Twitter- I promote on my own twitter page my book and pinned it to the top.
