As slim and dense as a flourless cake, not a word is wasted in this succinct primer for writing teachers. Speaking as a writer who has never taught, but is going to start doing so tomorrow (literally!), I found this book to be priceless. Whether I apply everything within its pages or not, there was no poor advice here, no sour notes, and nothing which did not make immediate and perfect sense. Fletcher clearly knows what he's writing about, and how to write about it. It will be worth referring to this volume again when I get to the end of the eight-week workshop I'm co-leading, and perhaps at points in between. I can enthusiastically recommend this to writing teachers at any level.
