Third-World Blood revealed the truth of Earth, her two sister planets, and the existence of magic. Now, five years have passed since the first signs of magic on Earth were seen, but the portal to the other two worlds still remains closed. Magic is still viewed as nothing more than illusion on Earth. Yet the events of one night may change that forever. A grisly murder on Earth reeks of magic, and a mysterious stranger appears. Lt. Brunson, a detective from Earth, learns firsthand the truth about magic when he is drawn into a chase across the three worlds for an unknown magical killer and the hostages that he has taken. In order for the hostages to survive, Lt. Brunson must join together with the stranger to solve and complete the Gatekeeperas challenge.
