Mei, Lili, and Jun have just three weeks to complete their senior year project, a portable translation device they call the monstrosity machine, which runs on magic and mathematics. "We only need to prove the concept," Mei tells her friends. Jun wants more than a passing grade, however. She wants that shiny golden insignia on her graduation certificate that says she's graduated with honors. With that, she's guaranteed a job in the best magic shops in Shēn Xiù City. And ai-ya, she needs that job if she ever wants to save enough money to study at university in the faraway Phoenix Empire. But getting their monstrosity to work proves to be more complicated than Jun ever predicted.
