About 12 years ago I tried writing a “Dragon” book for nanowrimo when I saw that new books with “Dragon” in the title sold 10 times better than other books.

I wrote about 30,000 words and then moved on to other things. I am now 65 and will soon be officially retired. The first thing I want to do in my retirement is go back to that book and see if it is worth finishing. It was very different from anything I’ve ever written or even read, and I think it might be a good thing to work on.
