Abraham Merritt tells a tale of awe and wonder as well as horror and dread to the speculative fiction and fantasy. The Metal Monster features the return of Dr. Walter T. Goodwin who first appeared in The Moon Pool. In the wilds of the Trans-Himalayan region, a quartet of adventurers led by Dr. Goodwin stumbles upon a tribe of human primitives forgotten since the age of Alexander the Great, and an awesome being of living metal commanded by the exiled Norhala. As Norhalas guests, Goodwin and his team witness the mind-boggling marvels that are the Metal Monsters way of life, and the unspeakable horrors it commits when Norhala takes it to war against her persecutors. An awesome battle between man and the metal beings ensues.
