I've read a few books on writing over the years. Some were just too silly (write words and draw arrows between them) or were focused on things I honestly don't care about (writing as therapy, or finding my inner whatever).
The things that interest me are:
* How do I make my writing better?
* What are the ways that various writers find that let the be effective at it?
Steering the Craft falls squarely and wonderfully into the first camp.
Le Guin presents a series of exercises along with supporting text and descriptions that drive home specific points about writing well. In addition, she discusses some of her own opinions about a few things in the writing field. It turns out she's simply a practical writer with both a great feel for language and an excellent ability to distil that knowledge into usable tools and techniques.
This isn't a long book, but it is quite clear to me that if you follow though on it by doing the exercises and evaluating the results honestly - possibly with a group of like minded people - you have a good shot at becoming a better writer.
I've begun that process, and I look forward to following it all the way through.
I expect Steering the Craft will be an excellent resource.
A great resource for writers, writing groups and classrooms, focusing not much on grammar and syntax but on the advantages and disadvantages of the various POVs, the use of adjectives and adverbs, dialogue and exposition.
