The new novel "Frontier" is a saga of an Earth ravaged by a devastating war between two marauding alien civilizations. Danger to the human bastion in Panther Ridge threatens not only from the living ships of the monstrous Gorgons or from the shock armored forces of the Cyphers moving elusive to the human eye - the world itself has turned against a handful of survivors, because one by one they succumb to despair, commit suicide and - worse, under the influence of alien pollution, they turn into disgusting Gray people - mutated cannibals, driven only by insatiable hunger.
