Query: Only Two Reasonable Options

I own this book because I am a lifelong student, not of UFO's, but of people who believe in UFO's. Whereas many books on this topic represent genuine attempts by serious people to come to grips with a phenomenon they do not understand; this "book" is comprised either of the ravings of a lunatic, or, a sad attempt to profit from both the gullability of the foolish and the fears of the delusional. There can be only these two options. In either case, if you are seriously considering buying it, I beg you to save your money.
