I spent time last week re-reading the book to refresh myself with action, look for gaps and major errors, and conduct a sanity check. 

The results pleased me but I discovered that I'd written two books around one premise. 

That didn't bother me. I'd been addressing a few continuity issues and realized that these issues existed because they were two books. I was creating a problem that didn't exist. Once I dismissed that as a problem, the next matter was, where does one end and the other begin? 

That also wasn't a problem. There was a natural break. I'd written the second book first. Then, reading it, I backed into creating the first novel. The gist is that the Parasam exists on a number of worlds. I started wondering when finishing the first novel, what's on the other end. 

There is no one 'other end', of course. I like calling it a worm tunnel for convenience but it's more like a series of inter-connected tunnels, and it's impact on locals isn't the same. I more or less realized that more completely as I wrote the prequel after the fact. 

More pressing for me is that I want both books to end their stories and yet be linked and continued. I do not want anyone reading either one to think they've been cheated. I don't like coming to an end and reading, "To be continued...." I won't do that to my readers. 

Naturally, as I reached these conclusions and acted on them, I realized a sequel. Ahem, or two. Or more. I realized a whole series. For now, though, I need to remain focused on finishing and polishing the first book of the series and getting it published. Then it's on to the rest. 

Can't wait. It really is a joyful feeling, this writing thing.
