I highly, highly recommend this book. However, before you rush out and buy it, do more research than I did. The author sells the same info in a three-part series, all of which you can snag for half the price of this book. And, since the last third is pretty much a rehash, you'll save yet more money by buying one at a time.
That said, I'm still thrilled I bought this book, even though I paid more than I should have. I get so easily bored by setting descriptions that I keep my own descriptions very, very brief. But Buckham opened my eyes to ways I can make setting descriptions work hard at characterization, backstory, and emotion, all without adding on more than a sentence or two of length.
Her examples were also top-notch, including a wide variety of genres (including many books I've read and loved) that show how setting descriptions are genre-specific. My eyes glazed over at the long, literary-fiction setting descriptions...proof that I'm not their ideal reader and a suggestion of where my antipathy to description came from.
Then there are the assignments, which really drive the points home. After working my way through this book, I feel like I just took a multi-week class, and my writing is better for it.
