Most important in terms of fiction I like is style and characterizations. I'm not fond of "low" styles of popular fiction with head-hopping, book-saidisms and other awkward writing gremlins, but neither am I fond of "high" post-modernistic styles such as stream-of-consciousness, refusal to use quotation marks and other artificial literary pretentiousness--yet I'm capable of enjoying a novel written entirely in second person. Go figure. Give me a character to root for, I can get through dark material--after all The Color Purple and The Kite Runner are favorites of mine--but if I basically dislike every character, especially the protagonist, I'm not going to make it through hundreds of pages. So yes, expect me to rate some literary masterpieces low and some cheesy but fun books high.
This was the textbook for the business writing component of the Katherine Gibbs secretarial course. I went on to college and beyond--and you know what? This is still on my shelves as a clear, lucid guide to grammar and business writing.
