I've read three books so far. Taken, Watchers and another earlier book that I have temporaily forgotten the title to. Yeah, my cone headedness is back. I have suffered this ailment all my life.
If you want to learn to write well, read Koontz. I am not kidding here. He handles back story with great skill, he isn't prone to over using cliches, and he doesn't switch POV often. When he does it is usually after a page break or in a new chapter.
I've recently read a New York Times best selling author who did switch POV's in the middle of a paragraph and did depend too much on cliche's and had way to many look, looking, and other similiar words. I'm not naming names. I will make a suggestion. You can buy a computer program that will hightlight in color all similar words in your manuscript. Let's face it, we writer's are human and rely on simple words when talking with people outside our writerly universe.
So, that's my two cents.
