If you were to talk with the author, what would you want to know? If she has plans to write another novel and what would it be about. She is a very gifted person I would love to meet.
If you could rewrite the ending, would you? No, I wouldn't rewrite any of it. The ending fit.
Is the story plot or character driven?
Disclosure - I received a free copy of the book which did not affect my honest opinion.
