This is another one I haven't got an explanation for. Where did the idea (which I can't tell you about because it would ruin the surprise) come from?
I know it was early on in my writing career. While I was looking for representation for Macbeth's Niece, I wrote a couple of other books, including Not Dead Yet... I queried agents for this one too, and a woman took it on. For a year she tried to sell it, but she got no takers.
I understand. It's hard to pitch a book that you have to read halfway...
