This one was personal. It belonged to my dad, purchased in 1974, the year he retired from the Army. He purchased many other creative writing books, but he never wrote a novel. He died in August of 2020.
The book is a very well written one for new novelists and I would definitely recommend it. The way my edition (the 1972 version) was written, the book provides all the key points in bold type to summarize what every novelist -- new and experienced -- would want to checklist through in writing their book.
Particularly intriguing is the authors' appreciation for intangibles of the writer, particularly the subconscious and even unconscious ways àn author interacts with his story. It was refreshing to see a book that was most likely a text for a college class speak of the intuitive elements of an author the way more popular books and even memes address those facets of writing.
Occasionally, the tone of the book was slightly condescending, but for the most part the authors are very supportive of those wanting to become writers. If you're thinking about it, pick up a copy.
