Messenger from Afar

The story is about a scientist who works at a university in Australia. He creates an Artificial Intelligence computer which receives a coded signal from space. With his companion, humans and the AI, they seek to discover a well-hidden secret through the centuries to avoid a possible catastrophe of humanity. On their way appear spies from foreign countries, secret agents from their own country and a secret brotherhood from ancient Sparta. They all seek the Holy Grail of knowledge for their own reasons and engage in an adventure that changes their lives, while at the same time looking at the human history they have been taught so far from a different perspective.
