I have never had the unhappy experience of being exposed to such incredibly poor editing. The typos and redundancies were very distracting. Repeatedly re-reading sentences and mentally editing every page interfered with the flow of the narrative. Also, if this fellow is a former Marine, he didn't pick up on the 1949 Marine Corps lingo as all my fellow Marine Corps buddies know it. And, Marine, as in "he is a U. S. Marine" is a proper noun not to be confused with "marine" as in marine life in the Atlantic ocean. Professional editing might have salvaged Mr. Keane's sincere effort.
