内容简介：
The second book in a trilogy about the interaction of Neanderthals and Cro-Magnons, "Spirit Fire" is an epic adventure that sweeps across pre-historic Europe, Asia, and Alaska, as the man who invented war embarks on a quest to conquer the world. Rumors of unusual people living in caves far to the east of the warriors' land attract warrior leader Warlog. His shaman, Rayloc, fears the strangers are really Droglits, servants of evil from deep in the earth who have come to destroy his way of life. In the east, Sotif, History Man of The Alliance between Earth People and Sun People, tries to guard his culture against changes that could induce Mother Earth to withdraw her blessings. But Warlog is intent upon breaking The Alliance by subjugating the Sun People and destroying the Earth People. Faced with this threat, Sotif races to find the Spirit Fire to bring hope to his people and help them defeat Warlog. The key to success ultimately lies in the hands of Tincolad, one of Warlog's warriors captured by The Alliance. Will Sotif find the Spirit Fire in time? Can Tincolad be persuaded to help The Alliance before it is too late for the Earth People?
