I bought this after following the Career Author Podcast (RIP),as it was written by the same people.
I read through it, then I read through it again. Bear in mind that the actual book is ~60% of the total page count, with the rest taken up by an interview with the author of the Virgin's Promise and other author resources.
Here's what I like: taking a different approach than the overdone hero's journey. Although this is mentioned, the focus isn't on the work that Campbell and others have done. It felt fresh for that reason, and kept me reading.
Here's what I didn't like so much: the three story method is difficult to encapsulate in a few words, which is why I read the book more than once. Bear in mind that I didn't purchase the workbook, which I plan to do soon. This is only on the book. Hopefully I'll have a clearer picture of the three story method with the workbook.
