I like books. Well-written books, which generally excludes most YA (sorry, everybody). I edit literary fiction in my spare time, and I eat up books with great prose and no pretentiousness. I also love good speculative fiction and frequently read classics.
I liked the advice in the first half of this book. Williams writes very directly about how to trim the fat from bloated prose. The second half wasn't as strong, though. It contains tips about how to keep an argument coherent, and for the most part, the tips here seem obvious, almost not worth writing about. I would recommend the first half to anyone trying to write more clearly, but the second half only to those who need serious writing help. Overall, a helpful read for my editing education.
