content: I'm OK with paying for eBooks. I bought this one, but was so distracted by multiple scan-induced typographical artifacts that I requested (and received) a refund about two-thirds of the way through the book. Free eBooks force me to tolerate some typos, as those books are done by volunteers and not for profit. But, an $8 Kindle Book sold by Amazon should be free of such nuisances. This one wasn't, and I'm basing this review solely on the poor quality of the eBook itself, not the content or theme of this book. It's a shame to hype the Kindle format while simultaneously selling a sub-standard version of that very format!
