The Alien Book: A Guide to Extraterrestrial Beings on Earth

These days, when we think of an alien, we conjure up an image of a black-eyed, large-headed, dwarfish being that has come to be known as a Grey. Greys have become a staple part of pop-culture, never mind just the field of UFO research. Yet, before the 1950s, these Greys didn t exist. Instead aliens came in all sizes, shapes, and bodies. This book investigates them all, along with eyewitness accounts of the people who have seen them. Covering hundreds of extraterrestrial life forms in more than 40 thematic chapters, this is an absorbing look at the mysteries of aliens on earth.
