Synopsis: "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." — quoted from the book's product page on Jamesaxler.com as of 2013-04-02.
