Savage Dawn — James Axler

OMNIPRESENT MENACE
In postapocalyptic earth, the Cerberus rebels fight the forces of alien tyranny over humankind. While the losses are often painful, their victories bring renewed promise. Forging a brave new world from the wreckage of the old, these dedicated warriors won't stop until mankind is once again master of its own destiny on earth.

PREDATORS OF EARTH
Kane, Brigid and Grant come to the aid of a race of serpent-human mutants caught up in civil war. Hope for the mutant race lies in an alliance with the advanced people who live in a verdant, secret place deep beneath the shattered islands of Japan. But their subterranean haven is under siege. In a battle to the finish, Kane and the others confront a prehistoric nightmare, retooled and fortified by the deepest mysteries of the Outlands.
