I have discovered an interesting phenomenon as a finish my books. I am almost sorry to publish it as my next one will be that much better.
In no way does this mean that I think my past works are no good, it is just that I get so excited and see so much potential in the next story that it is hard to focus on anything else.
When I finished my first book (Sigmund Shaw: A Steampunk Adventure), I was very happy with it (still am), but I had already had exciting ideas for the next one (Whisper of Bedlam Asylum) and new that it would be even better than the first one. As Whispers was being finished, I was already thinking about an Egyptian adventure with a very underused (although my favorite) character - and could be better than my first two.
Now that my third book (Tomb of Hannu) is nearing publication, I have the beginnings of a fourth one and I, again, think it will be my best story. I am SO excited about it!
My guess is that I am not unique in these feelings, but found them interesting enough to share.
