The Cave of Forgotten Dreams (Hardcover) (ISBN-13: 9781543414103)

Chris Gallagher is an associate professor of engineering at the University of Cincinnati. While on sabbatical from the university, Chris signed up for an archeological dig in Ard che, France, so he could study the structure of caves.
Professor Gallagher has always had an interest in self-hypnosis, teleportation, and time travel.

Chris's knowledge and paranormal skills are put to the test when his assignment accidentally takes him back in time.

Chris spends his first night in France sleeping in the Circle of Dreams on the hill just above Chauvet's Cave.

While in his sleep, Chris meets the artist who drew the four horse heads in Chauvet's Cave some 32,000 years ago.
