I wrote a series last year that was accepted for publication this year for release next year.
What this means is I'm editing books that I've essentially forgotten about for promotion next year when I will have forgotten about them again since I'll be knee deep in new writing by then.
Such is the writer's life. The 'up' of this is that I've rediscovered these characters and I like them. The 'down' of this is that I have to change a few plot elements to suit my publisher. The 'up' of this is that I'm discovering interesting sub-plots to weave in to help me change those elements.
I've discovered that anything I dread (like changing plot elements) is not as bad as I usually fear. I just have to take the plunge and once in, the water's fine.
Of course, check back with me in a month -- I may have changed my mind!
