Publishing has been a learning curve for me. I know there are books and articles out there aplenty, and I've read a few of them, but the process of publishing the book and finding the problems has been a trial and error sort of endeavor.
I think that now I'e done it, there are a few things that I will do in the future.
1. Have a few people I trust proof-read the novel for readability issues. There were three minor things that my daughter caught that I was able to fix later, but were troubling.
2. Trivia - Originally, the first two stories were one long book. Somehow, possibly because of this, the title of the second book made it on the the title insert page for the first book. This was caught prior to publishing the paperback, thankfully, and corrected.
3. Make sure the cover gets centered correctly. Again, this is a minor thing, but needs to be addressed before the first books go out to print. Small problems, now corrected.
It's been a very strange ride. I learned through the process that as much as you love your story, don't get caught in the trap that it can't be improved. The writer I was in my 20s, when Keyralithsmus was first penned, is not the person I am now that I am 50. The bones were there, but the flesh needed some toning.
I'd like so say I am older and wiser now. I think (hope) that's true.
