The Moon’s course alters itself as it passes by the lone Earthlike planet of an isolated star. But the planet isn’t big enough to be having a gravitational effect on the passing Moon, and then the impossible happens – the Moon is drawn into an orbit near the planet and then stops dead in its tracks. A spreading power loss means that Moonbase Alpha may be uninhabitable within two days, so Koenig leads an expedition to see if something on the planet is holding the Moon still. But the planet Arkadia holds startling discoveries – a cave full of human skeletons, and a wall-sized inscription in what appears to be Sanskrit. As Alpha’s power supply, heat and life support continue bleeding away, Koenig has to consider the possibility of evacuating his crew to a world sterilized by an unknown disaster. But when the message found on the planet is decoded, it raises a mind-boggling question: will the Alphans be returning to humanity’s ancestral home if they settle on Arkadia?
