Be warned that this silly paperpack is NOT serious scholarly research! However, it was more relevant than most mass-market fluff on the subject (perhaps without intending to be so), and there is a lot of useful stuff "between the lines" (again, quite possibly unintentional). The entire book is crammed with literally hundreds of "case studies" of alleged contact with multidimensional entities. Alas, many of the cases seem to lack credibility, and might well have been excerpted from the Weekly World News! This was a fun book to read -- even if it is full of B.S. -- and it's probably the best work that Brad Steiger has ever done.
