Helium-3 is a rare element that promises to solve all the world´s energy problems - and it´s been discovered on the Moon, prompting a breathless race between the Americans and Chinese.
In Shanghai, cyber-detective Owen Jericho has been hired to find a missing girl, but what started as a routine investigation soon develops into a nightmarish hunt, where he´s the quarry: there´s a crazed assassin hot on his heels, all because Yoyo accidentally stumbled onto a secret society called Hydra - and now their lives are at risk.
Following the Hydra trail takes Jericho and Yoyo round the world and finally to the Moon, where a billionaire entrepreneur is entertaining some of the world´s richest and most influential men and women in the Gaia, the planet´s very first hotel.
But Hydra has its own plans for the Earth - and the Moon. And nothing and no one will be allowed to stand in its way.
