Jason Zhou, his friends, and Daiyu are still recovering from the aftermath of bombing Jin Corp headquarters. But Jin, the ruthless billionaire and Daiyu’s father, is out for blood. When Lingyi goes to Shanghai to help Jany Tsai, a childhood acquaintance in trouble, she doesn’t expect Jin to be involved. And when Jin has Jany murdered and steals the tech she had refused to sell him, Lingyi is the only one who has access to the encrypted info, putting her own life in jeopardy. Zhou doesn’t hesitate to fly to China to help Iris find Lingyi, even though he’s been estranged from his friends for months. But when Iris tells him he can’t tell Daiyu or trust her, he balks. The reunited group play a treacherous cat and mouse game in the labyrinthine streets of Shanghai, determined on taking back what Jin had stolen. When Daiyu appears in Shanghai, Zhou is uncertain if it’s to confront him or in support of her father. Jin has proudly announced Daiyu will be by his side for the opening ceremony of Jin Tower, his first “vertical city.” And as hard as Zhou and his friends fight, Jin always gains the upper hand. Is this a game they can survive, much less win?

Jason Zhou survives in a divided society where the elite use their wealth to buy longer lives. The rich wear special suits that protect them from the pollution and viruses that plague the city, while those without suffer illness and early deaths. Frustrated by his city’s corruption and still grieving the loss of his mother, who died as a result of it, Zhou is determined to change things, no matter the cost. With the help of his friends, Zhou infiltrates the lives of the wealthy in hopes of destroying the international Jin Corporation from within. Jin Corp not only manufactures the special suits the rich rely on, but they may also be manufacturing the pollution that makes them necessary. Yet the deeper Zhou delves into this new world of excess and wealth, the more muddled his plans become. And against his better judgment, Zhou finds himself falling for Daiyu, the daughter of Jin Corp’s CEO. Can Zhou save his city without compromising who he is or destroying his own heart?
