Some books I read and feverishly take pictures of certain pages, in fear of forgetting some valuable wisdoms. This book I think I photographed a gazillion times (took pics of a gazillion pages, I mean). It confirmed what I've been reading over the last five years in the books on the craft of writing, only this time seen through the eyes of the computer that has analyzed bestsellers and extracted data on what sells and what doesn't and why. A good read to refresh your striving for excellence and, therefore, sell more books (this is not a formula on bestselling, it's a guide and a guess and a geek-out of two nerdy authors—I geeked out with them and loved it). Highly recommend.
