Query: There was a publisher?

This is one of the most poorly written books I have ever had the misfortune to purchase. Beyond the frequent misspellings and/or misuse of words, there were sentences that were cutoff, and references to diagrams that either did not exist or were mislabeled so as to make the reference pointless. While the topic does lend itself to referring back to previous points, the "author" shamelessly used the copy & paste method, to avoid taking a swing at it from another perspective. Fortunately, Amazon recommended a "bundle" that included three books, and so far, at least one of the others appears to have had a professional publisher (or at least an editor).
