Margaret lists questions to be answered before starting a book
Writing a story is a whole list of why questions.
Why does the heroine act as she does?
Why does the hero act as he does?
Why am I starting at this point in the story?
Why are there trust issues?
Why does the heroine feel vulnerable?
Why does she fall in love with the hero?
Why does he fall in love with her?
All of these need answering before you even begin to write. It’s a necessary and intriguing process but a very useful one, and I’m sure there are far more questions you can add to this list.
