Wanderers From The Stars by C M Chadwick
Are we quite alone as the owners of our 'blue planet?' This is the question a group of scientists ask of themselves when they uncover ancient -- and very unusual -- human remains in their work. They are able to analyse ancient DNA and link it to a veritable lost civilisation -- and with the appearance of flying craft. With their friends, they witness strange lights in the sky and the emission of great heat and radioactivity.
The truth is out there...and can be uncovered...
Then 'hold on tight' as the adventure takes the reader from such homespun evidence as crop circles and information they contain, to the mountains of Nepal where they encounter - of all things - the Yeti; and via the scientific laboratories of the United States, to the Mexican jungle, where a proverbial lost tribe awaits. Later, they encounter a visiting alien civilisation on a quest which they must satisfy at all costs. Inevitably, the latter's higher state of wisdom is compared to our own modern morality and our future questioned.
All this, and more!
With a wide cast of journalists, academics, enigmatic computer hackers, an eccentric clergyman and an assortment of villains, Wanderers from the Stars is an enjoyable, educational and enlightening story of adventure and science for fans of the 'lost world' genre, and is astute from modern cultural perspectives.
