Master of the Dark Gate

The Gate of Darkness stood open between the worlds, and the men of Earth faced invasion - from Earth! Gavin Black, newsman, ex-soldier, found himself drafted by unseen forces to wage war against that other Earth, and the barbaric hordes that threatened to overwhelm his world. He dared not refuse. But he found a love, a woman from the other world, and now it was impossible for him to NOT refuse.
