Centered on the far side of the Moon, this hard-core science fiction mystery weaves together quantum physics, the ruins of an alien civilization, political power struggles between Earth and the Moon, and a crisis threatening humanity's survival.
It features tidal locking, the Moon's history of volcanic activity (from 4.2 to 2.8 billion years ago), KREEP and the evolution of the lunar mantle, the energy potential of helium-3, and China's Chang'e 6 lunar far-side sampling mission. On the Moon's far side, in the South Pole-Aitken Basin, the protagonist discovers a quantum resonance device left behind by an alien civilization. Its energy fluctuations threaten the stability of Earth's magnetic field, while also igniting an interstellar war as nations vie for helium-3 resources.
