In this new tale, Cassie Severs and crew return from their climactic adventure in Turkey, and get back home to New York. Murro Vogt is sent back to prison, but Sandra NiKells begins concocting a plan for his future release/relocation, as her visions of their coming, greater mission, the Earth Gate, grow ever stronger.
The visions imagine herself, Murro, Cassie and David Severs at four corners of the world, originating from a base point of the Four Corners, southwest United States.
The plan Sandra devises to get Murro back with them involve Witness Relocation for him. As U.S. Marshall, Sylvia Weathersfield becomes suspicious of Murro's true motives, she dedicates herself to stopping anything on his part she perceives doesn't 'smell' right.
And indeed it doesn't, as the time grows nigh. New and old friends join the foursome in their race to meet their destiny - enacting the Earth Gate; a mega-Cross Gate which shall encircle the earth, catching up those of faith within in it, and taking them... beyond this world!
