This book is written from a standpoint that the reader is not familiar with any of the contents of the book. While I do believe that some may be in that position, it repeats established information from previous chapters in just about every chapter and becomes a bit mind numbing after a while, especially since this book will most likely appeal to those already familiar with the topics in the book, like UFOs, spook lights, mysterious large cats, bigfoot etc.

The author does a good job of referencing sources and his research, but with that, it felt like a lot of his explanations had excessive examples that were not from Oklahoma. It helps establish that it isn't JUST Oklahoma but it doesn't make Oklahoma feel special either.
