Whilst wrestling with my uncooperative historical timeline I came across these wise words on being an historical novelist from Bernard Cornwell!
Your job is not to educate readers on the finer points of Elizabethan diplomacy or Napoleonic warfare or villainous terrorist plots, your job is to divert and amuse people who have had a hard day at work. What will get you published? Not style, not research but story...your job is not to be an historian but to be a storyteller!
So the answer to my problem is? Concentrate on the story and the rest will fall into place! No excuses then!
