I have a new cover for my Search for the Light paperback, following advice from Chindi. The books now look part of the same series and historical.
If I could be convinced that it would work I would let CreateSpace convert the paperbacks into kindle format and end up with the e-books and paperbacks having the same covers. I’m a bit wary of that after someone else’s experience, in our writing group.
For the next book I will approach the cover in a different manner, creating my own rather than using the Amazon template and possibly getting some help.
