I enjoyed reading this book quite a bit, but there are some weird things about it. It was a good starting place to learn about some of the curiouser points in history, and it gave me subjects to do some deeper research on.
I'm not going to hide this review, but there are spoilers in it, so be forewarned!
The problem is that the author seems to have injected his own personal opinion into the reporting of the stories, rather than just the facts at certain points throughout the book. For example, some of the chapters, in my opinion, should not have been included, because they have not conclusively been proven to be hoaxes/deceptions beyond a shadow of a doubt. There is a whole chapter on the legendary heroine Hua Mulan and how she dressed deceptively as a man, while there has not been conclusive evidence to prove that she actually existed, a fact that is only casually mentioned at the end of the chapter. There is also one on Pope Joan, another person who is not yet proven to have existed. There is a chapter on the Patterson-Gimlin Bigfoot film, where the author states at the beginning that "the inclusion of the Patterson-Gimlin film in these pages will please some and annoy others, because there is as yet no incontrovertible proof that the film is a hoax." He also states later in the chapter that "In many cases of Bigfoot sightings, a misidentified bear is probably the most likely explanation." He's right, I am annoyed, mostly because both of these statements just prove to me that he was relying on his own opinion and trying to fill space in the book. At one point he makes a statement about Edward Plantagenet, 17th Earl of Warwick having been "thought to have suffered from what we would call 'serious learning disabilities'". That Edward was possibly mentally challenged is controversial, and is based on one line the chronicler Edward Hall wrote, where it says that he was imprisoned so long that "he could not discern a Goose from a Capon." These are just some examples of places where he would state things as being a fact when they have not been entirely proven, or examples of what seemed to be amateur research, where a quick Google search would have uncovered the same information.
My final word is that the book definitely had good points, and that it is a great starting place, but you're going to want to research further if you read it.
