British author and former director of investigations with the British UFO Research Association (BUFORA), serving in that role from 1982 through to 1994.
Randles specializes in writing books on UFOs and paranormal phenomena. To date 50 of these have been published, ranging from her first UFOs: A British Viewpoint (1979) to Breaking the Time Barrier: The race to build the first time machine (2005). Subjects covered include crop circles, ESP, life after death, time anomalies and spontaneous human combustion.
The Paranormal Source Book was so-so. It included information on alien abductions, angels, dreams, ESP, ghosts, healing, poltergeists, reincarnation, crop circles, UFOs and spontaneous human combustion (NOTE: it wasn't always supporting that these things exist). I found some topics covered in the book (especially dreams and spontaneous human combustion) to be very interesting, and I did learn new things, but for the majority of the time I was reading this; I was bored. It became almost a chore to finish it, and as a result, took me a while to get through.
Some of it was convincing, some of it not so much. Probably wouldn't read it again. 2/5 stars.
If you want to have a comprehensive overview of all kind of supernatural phenomena this is an excellent starting point: alien abduction, angels, ball lightning, cosmic messages, crop circles, dreams and symbols, earth mysteries, ESP, ghosts, healing, life after death, miracle images (like that on Mars), psychokinesis, poltergeists, reincarnation, UFOs, zoological mysteries, spontaneous self combustion... this stuff is in the tabloids for decades and probably will be for many more years.
