I saw this book in the store, and was impressed by both the introduction and the varied topics, that cover the different aspects of writing quite well. Having now finished the book, I'm glad that I bought it.
I always consider books about writing as guidelines, ideas of what you should consider, and not hard rules. Monica Wood has a slightly different idea of what description should be like than I have. The effect of some of her examples on me was different than what she intended. But that's one of the good things about this book. It illustrates its points well enough to let you judge for yourself if you like the style. There are many ideas to consider here, all of them written in clearly and with good examples.
I found this book a good inspiration to go back to an old story of mine, rewrite parts, and add details. Not because I found anything really wrong with my own descriptions, but because it made me think more about my characters, and how small things I encounter in my life can be incorporated into a fantasy story set in another time and place. This shows how a good book about description can cover everything from setting to characters, and inspire you not just where your style is concerned.
BTW, the book I have is an older (1995) hardcover edition.
