College student Xia Chi is drawn into a chain of mysterious deaths after the disappearance of Qing Zhi. His search leads him to Cerebrum, a vast system of connected realities where participants are forced into deadly games that test logic, nerve, physical endurance, and morality.

With each challenge, Xia Chi learns that the disappearances are only one piece of something far larger. Conspiracies, competing worlds, and the true purpose of Cerebrum push him toward choices whose consequences may extend far beyond the people he first set out to save.
