World Fantasy award-winning, bestselling author Robert McCammon makes a triumphant return to the epic horror and apocalyptic tone reminiscent of his books Swan Song and Stinger in this gripping new novel, The Border, a saga of an Earth devastated by a war between two marauding alien civilizations.

But it is not just the living ships of the monstrous Gorgons or the motion-blurred shock troops of the armored Cyphers that endanger the holdouts in the human bastion of Panther Ridge. The world itself has turned against the handful of survivors, as one by one they succumb to despair and suicide or, even worse, are transformed by otherworldly pollution into hideous Gray Men, cannibalistic mutants driven by insatiable hunger. Into these desperate circumstances comes an amnesiac teenaged boy who names himself Ethan—a boy who must overcome mistrust and suspicion to master unknowable powers that may prove to be the last hope for humanity's salvation. Those same powers make Ethan a threat to the warring aliens, long used to fearing only each other, and thrust him and his comrades into ever more perilous circumstances.

A major new novel from the unparalleled imagination of Robert McCammon, this dark epic of survival will both thrill readers and make them fall in love with his work all over again.
