$40 seems really expensive for a short book like this. I&#x27;d love to read a few objective reviews to see if it&#x27;s worth the price.<p>For $10 I&#x27;d buy without thinking. For $20 I&#x27;d probably buy with an Amazon type consensus. But for $40 I&#x27;d need a few trusted reviews before a blind purchase from a self publish.<p><i>Not that there&#x27;s anything wrong with self publishing ... just that there&#x27;s no judge of content or quality as there isn&#x27;t a &quot;style&quot; for the publisher.</i>
