The Ufonauts

In this amazing book, Hans Holzer, renowned psychic investigator and ghost-hunter, now turns his sights on another kind of game. On beings from beyond our galaxy. They say they are here to warn us and help us not to destroy ourselves. Could they have some other purpose in mind? Why are they really here? The Ufonauts presents overwhelming evidence for the fact that they are studying our life forms and taking specimens of plants and animals. And people.
