So I am back to rewriting.
Having stated earlier that I prefer plot over character, if I have to choose at all, I will remake the novel to reflect this better. Rather than being the story of a person I will write a story of events, ie plot.
Needless to say the working title needs to be changed as well. Instead of being about Arthur it will concern itself with what happens around him, and in his wake. Should paradoxically enough give me more time to flesh out a few other characters.
