The book Aliens in the Backyard has the word synchronicity right on it's cover. The overall abduction phenomenon might seem to have a defined set of boundaries, those crumble when you examine it more closely. Then you realize it's a lot more mysterious than just little scientists coming to visit us on metal spaceships.
Trish and Rob have written a book that looks at some of the more bizarre aspects of the overall lore surrounding UFOs. Their examination of the phenomenon includes divergent topics like synchronicity, psychic experiences, the occult, planetary empaths and the military aspects. They are both professional writers and their skill shows through in the well written book. It is also a personal journey where the authors play a role, so it reads like a first person detective story.
