I have just downloaded Career Novelist by the literary agent Donald Maass from his agency’s website. My first impression is that it is probably essential reading for would-be novelists. Thanks to Gary Gibson for pointing me in the right direction.
The Canadian SF author Robert Sawyer reckons this book is one of four must-read books for fiction writers. I would certainly agree about the two Orson Scott Card books he mentions and I would add a fifth: Becoming a Writer by Dorothea Brande is an inspirational book, which never fails to enthuse me about writing whenever I re-read it.
