This new edition of Colin Wilson's classic volume examines an enormous range of both famous and little-known UFO encounters. Tapping into his vast knowledge of the occult and paranormal, Wilson is able to draw parallels between events that others have missed.

For readers unfamiliar with the variety of phenomena associated with UFOs, this is the ultimate introduction. You'll see how UFOs are related to other unexplained phenomena, including ancient tolklore, time slips, and psychic travel to other worlds. Wilson examines the history of UFOs and pays special attention to the ideas of famed researcher Jacques Vallee.

More importantly, based on his knowledge of non-traditional subjects, Wilson has a conclusion as to why UFOs are here. His ideas are far different than those who seek only to scare us and you'll be fascinated by his unexpected conclusions.
