Alas! After a decade of owning this book, I completed it today. :)
Once upon a time I thought I might like to be a professional storyteller, hence why I purchased it. I am not certain that is a goal any longer, but I love telling stories. Presently, I am delivering speeches from the Storytelling manual at Toastmasters. That has rekindled my interest in this. That and the fact this book sits in the big pile of To-Read in the basement.
What is noted is that Cassady has included a wealth of good stories. Almost all included I could see retelling myself.
Each chapter provides tips and other things to concentrate upon while speaking, writing a speech, or preparing for a speech. Much of it reinforces what Toastmasters teaches. A couple things are at odds with what I have been taught; thanking the audience, for instance.
Overall, I think this is a good book. I felt some topics, notably the end where delivery was addressed, received short-shrift. It is always difficult when writing comprehensively to do everything well. There's more to say, I feel, than one paragraph about enunciation.
Anyhow, if you re looking for a good book about storytelling, I would recommend this one.
