Plotting and Rewriting My Novels

I don't plot my novels in detail, but I usually have some important scenes in mind. I only have a few more chapters to write before I finish Monday's Child, a traditional Regency novel, the follow on from my published novel, Sunday's Child. Unfortunately, a scene I really wanted to include when I wrote it doesn't work. Deep, deep sigh, I'll have to rewrite it using different circumstances. I find it very hard to - as the saying goes - kill my darlings.
