Query: Zero cost, zero value. Don't waste your time downloading this.

Zero cost, zero value. You've heard it said -- "You get what you pay for." It's very true for this "book." I've read other very good zero cost books from other authors - real books that have whetted my appetite to go and PAY for the authors' other books. And I think that's the objective in advertising zero cost books - to introduce you to authors you might otherwise not read. But your 5 or so seconds downloading this "book" has more value and you should be compensated. This "book" should be deleted from the Amazon list. Really. It's that bad.
