I know I haven't posted any idea for the marketing and promotional ideas for your book[s] in a while. So to make it up I'll be posting three of them now.
Many times, when I write a review I include a song which the book I was reading reminded me of. When the author read my review she/he said it had capture the essence of the story. So why find a song which does just this. Try to use it in any marketing/promotional activity you might be doing.
