The encyclopedia of the unexplained - Judy Allen

?The Encyclopedia of the Unexplained is a comprehensive guide to the mysterious and strange, whether natural or unnatural. Even with today's hi-tech science, many events and ancient mysteries, such as crop circles, ghosts, the Holy Grail and the Nazca Lines, remain unexplained, with many theories stirring the imagination. Some famous enigmas, such as The Bermuda Triangle, have now been explained by science, but still hold an allure of mystery. The Encyclopedia of the Unexplained will also uncover some of our ancient superstitions and symbols, from why black cats are lucky to how Feng Shui is supposed to change life for the better.
