Zachary Yin and the Emperor-Dragon

Zachary Yin knows nothing about China. In school, they are taught only Western history and mythology, and his Chinese mother doesn't like to talk about her past.

It's time to take an express course, because Zach's mother has been kidnapped by demons who are trying to open a portal to the underworld, and the spirit of the First Emperor of China has possessed his augmented reality glasses and is commenting on everything that is happening.

Now Zach has only fourteen days until the Ghost Month to team up with one of the most notorious tyrants in history to reach the Celestial Empire, steal powerful artifacts, fight for the peace of mortals, and save his mother.
