Series books for Kindle - Do you differentiate your covers or keep them identical?
For people who have series books (fiction or nonfiction) do you use the identical cover and just change the titles or keep the design layout but change images, etc?
Just wondering how people have done this or have experimented or ran any tests and found any interesting results.
Thanks in advance for any info...
