Structure (Chapter 2); 'Try to avoid predictability. Start at the middle, then do the end and finish with the beginning.'
Language (Chapter 3); 'Avoid cliches like the plague. They make all writing dull as dishwater. If you use mixed metaphors, you are skating on thin ice and could end up in hot water. An inclination towards hyperbole, or exaggeration, is a million times worse than any other problem. Don't confuse tenses because publishers will rejected manuscripts that have been containing obvious errors. Don't use a big word when a breviloquent one can be just as effective. And finally, never start a sentence with a conjunction and punctuate correctly?'
Editing (Chapter 6); 'Revise your work at lest five (6) times before you sended it to a agent or an publisher.'
If you follow the steps that Frey has so carefully detailed in this book, your unpublished days will be numbered. Around 15,000.
You might want to combine this book with Stephen King's "On writing", which has fewer tips, but is worth reading anyway.
