For Barbara and her friends the world as they know it is about to be turned on its head. It began with hallucinations and a feeling of foreboding that the universe we took for granted was not quite what it seemed. The everyday laws of physics are wiped out in an instant as mankind realises that there are forces beyond our little planet which regard our existence as low as bacteria, to be treated with the same level of contempt and disregard. We discover that we are not alone when we are visited by a species so alien that they freeze the blood, making us question our place in the universe and our origins. To our visitors it is a question of scale. Mankind finds that we are not as advanced as we thought we were. The human race is set to change. Whether we like it or not.
