In 1994, I read the Celestine Prophecy. It was a good story but kind of new agey with lots of supernatural inferences. I wished it had more solid information about the new discoveries being made in the field of health and the human body.
It didn't, so I wrote "The Gafferty Perspective," a novel about a man who goes on a quest and keeps coming across weird information and people who believe it. So, pretty much the same format as Celestine, but with a more grounded approach. It tells the story of medical researcher Gerald Gaffety and his theory about human health, particularly the need for keeping cells happy. There was some DNA speculation and energy medicine ideas thrown in as well.
I published it myself in 1997. The book was characterized as "science fiction" because, well, some of the information in it was hard to believe, and it was definitely populated with fictional characters.
The first novel "The Gafferty Perspective" was quickly followed by its sequel, "The Gafferty Momentum," written in just a month, probably off the momentum created by writing the first novel (and thus its name.)
