The second book in the Otherworldly Martini series.
After the "Gospel of Chaos" incident, Lewis Henry abandoned his gun-making plans and devoted himself to enjoying student life at Cosmu with his close friend, Ibita.
But the good times didn't last. Ibita suddenly fell gravely ill, while Princess Serna took advantage of the chaos to coerce Lewis into going to Tianzhou, an ancient and mysterious eastern kingdom, to find the missing Kasfulen archaeological agent and Lewis's mother in this life, Rona Henry.
At the time, Tianzhou was shrouded in the shadows of major criminal cases involving lives: the Water Nation's waterbender Ling Tong Zhexang had defected, and the Yin family, a clan of mechanism-craft masters, had been wiped out. One careless step could drag him into the fray.
Can Lewis pick his way through the sensitive threads of this tangled web in Tianzhou, complete his mission unharmed, and return to his family and the one he loves?
