Earth Moon, Great Archive. Chronicler Tsai Yini monitors the tachyon communication system, which transmits data faster than the speed of light. When classified results from an astrobiologist’s research are leaked to her, she cannot believe what she reads. The report reveals that intelligent life forms exist on a tropical planet in the Gliese system.

Their civilization is still in its infancy but revolves around an artifact of unknown origin that seems to influence their body chemistry. But there’s more: the astrobiologist who uncovered this artifact has undergone a baffling evolution of his own, and he’s now en route to Earth!

Yini suspects he carries a danger far greater than anyone could imagine. To stop him, she must make unimaginable decisions that could determine not only her fate but the future of the universe.

For fans of Cixin Liu, Andy Weir, and Frank Herbert, Tachyon: The Weapon delivers a high-stakes adventure where the line between discovery and destruction blurs.
