After the events of Bai Tide, CIA case officer Bai Hsu is safely tucked away at Headquarters in Langley, Virginia. Bored and frustrated, he's starting to doubt he'll ever return to the field until he's given a difficult new assignment: Track and investigate the mysterious Ghost Cartel, who may or may not already have hooks in our government. With secrecy of the utmost importance, Bai accepts the mission even though he knows he'll be out in the cold. With no official cover, no backup, and no resources, Bai has no choice but to infiltrate a shadowy organization few know anything about. Tangled in a conspiracy that will pit him against warring cartels in Mexico, this is Bai's most impossible mission to date. It will test him, make him question himself and the organization he works for, and ultimately rip away everything that's ever mattered to him.
