This book was not bad, but for me it was disappointing for the following reasons.
1. It was in large part just rehash of all the old classic cases that people who are in to this stuff will already know pretty well: Philadelphia Experiment, Mothman, Roswell, moon landing conspiracy, bigfoot etc etc. To his credit, the author presented some new pieces of some of the material that I had not seen before but not really anything that made a difference.
2. Much of this material is not fact based... the author raised a number of questions but had no answers other than to pose some ideas and suggestions, any (or none) of which could have plausibility.
3. This was not really excellent writing or editing as there were a number of grammatical errors and erroneous word choices (although I know we've all probably been confounded by auto correct a time or two. Perhaps I'm too picky but sometimes the quality of the writing reflects the credibility in my mind though I know that can be like judging a book by its cover.
The best thing I can say about this book is that it DOES contain a lot of cases and to those who aren't familiar it should seem very interesting and perhaps mind expanding.
