In the Meat Zone

Greg Cebulski, recently divorced and sequestered in his lakeside cottage with his dog Banjo, nearly misses the news. Extraterrestrials have invaded the planet.  The earth's major cities and most of its population are devastated. As low-flying triangular spaceships float overhead, Greg is quickly attuned to the necessity of survival. To his relief, he discovers he is not the lone man on earth. He is joined by two survivors, a woman and a small boy.
 
Their tenuous sense of security is short-lived. Relief and a growing family tenderness turn to dread when the menacing Fendiuk family arrives. A wounded man Adrian who accompanies them, is afraid to tell what he knows.

As the war of the worlds rages, alien sightings in the forest increase. Heavily armed Greg, beset by danger and isolation, battles both the aliens  and murderous humans.

Written with the dramatic verve of the pulps, and the skill of a literary master, Sean Simmans's paranormal horror sickens and fascinates as murder, torture and vengeance flourish and then abate.
