My novel is 1,000-2,000 words for each chapter. I have been planing my story for about two years. I always start with a beginning and an end and try to see how I can reach it. The story is the journey, so naturally, I don't know how long it's going to be yet. Maybe five years if I keep writing it. I have a few arcs ready to be used. The challenging part is to find out if or when I can use them.
Here's my story if you want to check it out.
