I purchased this book way before I set pen to paper to start my writing career.
I have now had accepted for publication three books, which are part of a series of 12 which hopefully will also be published.
This is a modest little book, but extremely useful and full of common sense ideas. The writer is now a publisher himself, so he writes from both perspectives.
Stewart covers every conceivable writing style including for Cinema, TV, stage, comedy, radio and children. I don't write fiction but he does cover this in great detail. He also covers all the drawbacks, problems, headaches and general complexities of the whole publishing business, so you understand what you need to know to make the best of your own writing.
My copy is still on the shelf and referred to quite frequently. I would definitely recommend this to anyone contemplating a writing career.
