There are many unexplained accounts of alien encounters and strange occurrences which have been documented throughout human history. These encounters could just as reasonably be interpreted to have been the result of interactions with a parallel world rather than an extraterrestrial visitation. In fact, the field of theoretical physics has produced many parallel world theories, although the possibility of parallel worlds is generally considered the stuff of science fiction.

One day, however, near a small town in Southern California, in a canyon where the O’Brian’s ranch is located, a faint, nearly subsonic sound began to make itself apparent. At first, the sound was relatively easy to ignore, but over time it seemed to bore its way into Wolf O’Brian’s consciousness. Eventually, the sound became so insistent it compelled Wolf to try to find the source. What he discovered was beyond belief, a gateway, a portal leading to a very different world, a parallel world.

After two years of amazing discoveries and growing friendships between the O’Brians and the benevolent beings from this other world, a moment of naïve altruism results in the start of an insidious alien invasion of the human world. A squadron of U.S Marine fighter pilots become the first victims of an alien, brain-infesting parasite and they quickly spread the invasion aboard the deployed warship, USS Wasp.

The aliens, however, soon discover that humans are much more difficult to control than other species they have dominated and enslaved in the past. The poorly planned, prematurely launched invasion of the human world is set in motion by the clueless Glort-Marine hybrids. Plots and plans are hatched and foiled, battles are fought in three dimensions, and our intrepid heroes, Wolf and Chase O’Brian, ultimately find themselves in the complicated and challenging position of trying to save the world.
