It is the beginning of the twenty-first century. Earth is unstable due to the influences of good and evil, and the immortal gods from the Council of Elders and the Brotherhood do not know its fate. The protocol requires summoning a human Observer, who reports to the gods about mankind's state of affairs in an effort to return equilibrium to the planet. Catriona Blair is chosen, and taken away to the Thirteenth Realm. Forced to spend time in the proverbial heaven and hell, she is manipulated by both immortal groups. During her trial, Cat discovers the reason she was selected, and that one group is trying to keep her true identity secret. It's a secret she is not aware of, until Heron, her trusted Advisor, explains the magnitude of her role. With his assistance, they must keep Cat's identity hidden before it's discovered, and the course of her fate and Earth is forever changed.
