Brief, concise, and useful. A good place to start if you want to see if Holly Lisle's other writing ebooks would work for you. Follow the steps, trust your creativity, and you'll have the basics of the story you're trying to write - and a somewhat-sparse-but-workable outline of an entirely new story. I have to admit I felt kind of accomplished at having written a full outline for something totally new in less than 24 hours, even though I don't think I'll actually pursue that story anytime soon.
There were quite a few references to Lisle's other books, but I didn't really mind that. I mean, most 99 cent books in the Kindle store are basically teasers for other books.
I do think I'm going to have to go through the Create a Plot Clinic, since I bought this book hoping to use it to work on something specific, and most of this book's exercises were focused on entirely new books. (I know I could apply the same exercises to that specific book, but I also want to go into more depth with it.)
One issue: this book contains broken links, and also many references to "worksheets" which you need to sign up to the author's website to access, and which I could not find anywhere on the site even after signing up - I suspect it may have something to do with the fact that I bought the book from Amazon and not from the author's website, but yeah, I just had to ignore any mention of worksheets. I mean, I think my exercises turned out fine anyway, but it was a bit frustrating and confusing.
