Past The Half Way Mark

Wow, it's finaly happened. The word counter has ticked past 50k. I am on the down hill race to the finish. The story is telling itself. The characters all have their voices and one of the key feautres I planned - historic letters and diaries of the past working there way through the story has died about 20k words ago. The character seem to want to tell their story without the distant past. I am not convinced this is correct but at the moment I am letting them tell the story. The next draft will be mine!
