Query: This book is not worth the read.

(...) This book was poorly written by someone who is claiming to be an expert, and yet can't articulate his arguement with substantial data. His "feelings" about what a DL man is, cannot be set as the final say in the matter. He shared his experience on the Oprah show and on the book cover. The rest of the (...) is full of personal ramblings. Your eyes have already been opened to the issue. Choose another "expert" on the matter... this guy is weak!
