This had an unfortunate number of typos, and illustrations that were more distracting than endearing.
That said, this slim little book is a plotting and characterization boot camp! It's super concentrated and delivers mini lessons on almost every aspect of a novel, plus revisions. While I thought it might be more focused on the synopsis, it takes a holistic approach and provides ways to improve your book while you're creating the synopsis itself.
Surprisingly useful, and probably good for any writer to leaf through.
