   Summary

   Three hundred soldiers died trying to stop the impossible.

   Faced with a power beyond anything humanity can comprehend, China’s government is given only one way to prevent further devastation: fulfill the alien ruler’s single demand.

   One human.

   Elio never asked to become the obsession of an emperor from another galaxy. But Ayden has spent years watching him from the stars, and now that he’s finally come to Earth, he has no intention of being separate from him.

   After all…

   Invading a planet is a small price to pay for the person he’s chosen.
