My very lovely cp made a remark about my latest chapter yesterday that made me realise that I had in fact taken a wrong turning. I had lost focus on the main story and need to rethink.
It is better to rethink NOW rather than when this is delivered or even worse after I get thoughts back from my editor.
I have been there, done that and I suspect sometimes it is part of my process. It is far from convenient BUT ultimately the aim is to provide the best story possible.
So it is a change of hero and change of location and fingers crossed -- the story will be far more emotional. Just not pleasant in the meantime for me!
