I am playing around with cover art ideas and have some that are quite interesting. I have added a brief tag line, not quite a subtitle, to the cover to indicate the genre. Frankly, the artistic photo of the guns that I am thinking of using should clue people in to the fact this is not a kid’s book and they ought to expect violence.
I have found myself adding (in much smaller font) a tag line. This is an example of one tag line:
A Gentleman Assassin Never Tells
Would the addition of a tag line that would imply genre or character improve the chances of it being selected, even momentarily? If the reader doesn’t open the book, it won’t matter how compelling it is. Or do tag lines just add clutter?
What kind of tag line would best serve this purpose?
