Have you considered that the cataloger copy and pasted this from a website and that the summary on the website differed somewhat from what is on the dust jacket or other location on the book?
Wow, Pete. That's quite a switcheroo from the more common sin of plagiarism ... to put quotes around a made-up narrative, as opposed to putting no quotes around a genuine narrative. I have never seen this phenomenon. One is called plagiarism. I wonder what the other one is called. "Putting words in someone's mouth"?
