Query: Very Functional

This book has great insight into what it takes to be a creative author. My only complaint is the content of some of the sample stories. I realize they are very well written and serve the intended purpose. However, when limited pieces of suspense and crime stories are included it leaves the readers (who are simply trying to to get an education) with a terrible feeling in the pit of their stomach.
