I've read all the books in the Elements of Fiction Writing series and this is how I'd rank them.
"Scene & Structure" "Characters & Viewpoint" "Beginnings, Middles & Ends"
The above three books are invaluable -- must reads. They are the best of the series, in my opinion, and are packed with good information on every page. Well-done.
"Conflict, Action & Suspense" "Description" "Plot" "Manuscript Submission" "Setting"
The above five books are good, solid reads. Again, they contain good information and cover the subject decently.
"Voice & Style" "Dialogue"
To me, the last two books need to be rewritten. They are by far the weakest of the series. Both suffer from an annoying style, particularly Dialogue, and both are very skimpy on real information. Neither one is very helpful.
This is the order in which I'd recommend reading them.
