It is 3289 BCE when rumors of unusual people living in caves far from his land attract the attention of warrior leader Warlog. His shaman, Rayloc, fears the strangers are servants of evil determined to destroy his way of life. Meanwhile, 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—while Warlog focuses on severing that alliance, which has lasted for hundreds of generations, by subjugating the Sun People and destroying the Earth People. Faced with this threat, Sotif races to find the Sprit Fire to help his people defeat Warlog. But the key to success lies in the hands of Tincolad, one of Warlog’s warriors who has been captured by the Alliance. Now only time will tell if Sotif can persuade Tincolad to help find the Spirit Fire in time—as the fate of the Earth People hangs in the balance. The second book in a trilogy about the interaction between Neandertals and Cro-Magnons, Sprit Fire presents an epic adventure that sweeps across prehistoric Europe, Asia, and Alaska, as the man who invented war embarks on a quest to conquer the world.

Novice archaeologist, Sandi Hartwell finds exactly what she wants in the hills of northern Pakistan—hard evidence that Neandertals and Cro-Magnons successfully produced offspring together. Her future looks promising, but less than one month later, the attacks of 9/11 will change everything. The enigmatic Neandertal expert, Garret Chambers, manages to get Sandi and the crew back into Pakistan to the site of their discovery. New discoveries abound, but then Sandi and Garret find themselves surrounded by murderous terrorists. Rescued by a flying saucer, she is taken to an extraordinary civilization governed by an arthritic old man named Ronaldo. There Sandi is plunged into a diabolical plot. After centuries of specialized breeding, a group of the descendants of the Neandertals, led by the charismatic Solero, is preparing to arm a global network of terrorists with WMD. Having felt the power of the ancient Spirit Fire, Sandi joins forces with Renaldo to stop Solero’s plan. Using a sixth sense that even she can’t explain, Sandi frantically follows the fossil trail of a legendary priestess named Kectu to discover the key that will destroy Solero’s plot. Drawn together by shared peril, she falls in love with Garret, but their love will be tested and her perception of the world will be pushed to the limit.
