I found the key.

I think I found the key to Ghostlander.

I'd been trying to find it for weeks, and finally last week decided I had to get to writing and that I'd just have to hope I'd stumble across it later.

Today, I think I did.  I'm 18K words in.

Most often this happens by asking myself questions.

For instance, this time, the problem was:   I have a ghost story which involves the Pilot Butte Inn and a bunch of missing guests.  But how do I bring Faery into it?

As soon as I figured that out, I realized that I had all the pieces to make a plot work.

That moment when I know it is going to be a book.
