Jeff Browning is a teenage boy who, following the mysterious disappearance of his father (a brilliant physicist), finds a portal in his father's office that transports him to another dimension. The dimension is populated by fantastic and dangerous creatures and also an advanced society of humans. That society, while very different from those on earth, is oddly similar, in some ways, to the society in which Jeff grew up. As Jeff looks for clues regarding what may have happened to his father, he is accused by some of being a spy while thought by others to be a prophesized figure . . . who may be the key to victory in a developing war.
