I just heard about a "Global E-Book" contest sponsored by Dan Poynter's organization. Entrance fee is $59 (discount for multiples) and deadline is June 30th. Categories include covers, multiple nonfiction topics, and multiple fiction topics. You can check it out at http://awardsforebooks.com/
I don't know any more. Investigation is key since $$ is involved. Good luck if you enter!
