The cult classic on UFOs, alien abductions and the strange world of abduction researcher Budd Hopkins. Written by journalist Jim Schnabel at the height of the abduction craze in the early 1990s and originally published by Penguin. Now in e-book format for the first time.
A decent history of the UFO phenomenon - a bit 'been there, done that' for me, but I recommend it to all you non-Forteans on my Friendslist, if for some reason you ever need to know any of this stuff - interspersed with a few genuinely interesting psychosocial hypotheses to explain the phenomena.
(Except nobody seems to be reporting the phenomena any more.)
