Did alien visitors manipulate Earth’s ancient civilizations?
In the Seeds Of Civilization novels a Seattle aerospace engineer and his team follow a trail of strange artifacts in a search for the truth about the age and origin of Earth’s earliest civilizations. Each new investigation reveals answers that are truly “out of this world!”
Tractrix, Tsubute and Triangle give adventure-lovers a glimpse of real life archaeological mysteries—the ancient Maya of Mexico, the submerged Yonaguni monument in southern Japan, and an ancient sunken city in deep waters off Cuba. Find the series in BookSense bookstores—including The Book End and Bob’s Beach Books, sponsors of the annual Oregon Author Fair events. The novels are also at public libraries across the U.S. and at such diverse sites as El Tecolote Libros in Todos Santos, (Baja California Sur) and Borders at McCarran Intl Airport in
Las Vegas. Online, the novels are on all major bookseller sites.
