Certain Strangers (Unabridged‪)‬

Mankind is putting Mother Earth at risk, with serious consequences. Their rescue lies in an ancient culture that arrived on the Australian continent many years before humans walked the Earth. They had come in craft made of light, which turned to crystal on contact with the Earth's atmosphere. Three crystal shards from these craft were removed, as they could be brought together if the need arose to protect Mother Earth. In a bid to conserve these crystals, they were concealed. One shard was hidden on Mount Olympus, one on a small island off the Welsh coast, while the location of the other is a mystery. Galen Cairns learns of his late father's quest to bring the shards together and protect the future of the human race. It's a dangerous undertaking, but Galen has to try. He finds himself engaging with powerful opposing forces, but with the help of unlikely allies, can he set in motion the quest to save Mother Earth?
