Jonah Barnes didn't think he'd end up on the Moon with no job and his brother's ashes in his hand luggage. Chang'e lunar base couldn't care less about its newest arrival and that suits Jonah fine. All he wants is to escape his dark past and start a new life mining Helium, until a chance meeting in a bar sweeps him into the raging undercurrent of the Moon's racial tensions and politics.

Now, Jonah is on the run and wanted for murder. With his new friend Lucien, he must grope his way through the pitch-black tunnels of abandoned mines to reach the oppressed Moon Folk's secret colony. When he gets there, Jonah must fight to overcome his past if he is to have any chance of saving his new friends from a madman who will stop at nothing to enslave the people of the Moon and seize control of the incredible wealth that comes from supplying the world with energy.
