Four worlds that must be visited.
Aliens are spying on Earth from one of the four worlds that make up the Warden Diamond. But it is impossible to send agents to any of the four worlds because of unique microscopic symbionts that make it impossible for visitors to leave the Diamond.
Seeking a unique solution, each of the four worlds making up the Diamond is sent a person whose mind has been stripped of everything and who is now controlled by an agent of the Confederacy.
Cerberus is the second planet to be visited. Qwin Zhang is stripped of her personality and left naked on the planet with her mind now occupied by one of the Confederacy’s best operatives. Can she/he survive long enough to find out the truth about the deadly planet known as Cerberus?
