2.5 stars actually.
Looking for some basic structure on the short story? This is probably not the book you want.
It does however try and persuade you not to write. Which is really very sad. One should not dissuade people to have creative outlets, which is my reason for the two stars.
On the upside: If you are in a writing group (and ignore the negative bits) there are some excellent exercises, and guideline on what to do and what not to do when in a group to be helpful to each other.
The best and most helpful bits: There is a great short glossary of terms and definitions used when writing mainly short stories and more; and a story check list that looks to be helpful.
I suggest borrowing a copy to make notes, copy the glossary, and checklist then return it. That's what I did.
