Ive heard its best to pick up where one leaves off.
It makes sense, but it was never a philosophy given to writing. Especially when there is a prolonged gap. You just can't get back to it. The rhythm changes, any cadence established gets lost. You can try, Im sure, but the fracture of time will stand like the grand canyon in the story.
Plus I know I write better now then I did two or three years ago. I am however not sure any of the characters are as good as some I have left here sitting on a shelf waiting to be read again. So what's next? the rewrite.
I tried to emulate DomLuka in a little way with DnCW Multiple characters and story threads. Spur interaction with readers as they tried to guess who was going to end up with whom. I failed. I built a story that became top heavy. A story that was sitting on a single central character. The story became unstable, and began to lack a defined direction. It needs to be rewritten. From chapter 1 onwards. somethings may stay. Others may go away. Im not sure, but I know it has to be done, because as the story is now, I can't write anymore of it.
It's hopelessly broken.
