Query: This is a joke, right?

The reviews for this "book" led me to believe it was an actual work of authorship. When I received the volume, I discovered to my chagrin that it was apparently put together by a computer, one with an inordinate fondness for exclamation! Points! Worse, it has bullet points, like the dumbest of how-tos. I made several good-faith attempts to read this collection of alphabet letters, but was stymied every time by its incoherence, lack of narrative structure, inability to present a focused and consistent voice, questionable scholarship, and all-around painfully amateur quality. I would love to read a coherent, literate history of Confederate (and Union) spying during the Civil War, but this. Ain't. It. Those positive reviews must have been friends and family; I can't imagine an objective outsider having anything good to say about this lead balloon. I wish I could get my money back!
