Query: In a word -- T-H-I-N.

I should have known -- when the lines are so spaced apart, the print large, and the book still thin, there may not be much in the book. There are exceptions, for sure, but not this one. I agree 100% with the resentful reviewer -- and am most grateful I got the book as a bonus and didn't pay retail for it. Doesn't even seem like a "rehash" to me -- sometimes they make you rethink some things -- this one does only skimming on the surface. Skip it.
