This is the second book in a series, which is based on the premise that humanoid aliens landed on earth tens of thousands of years ago. They bred "Big Foot" yetis as helpers and created humans with which to interbreed. The aliens became the ancient gods of the Egyptians. Going into cryogenic sleep for centuries at a time, the aliens come back from time to time to wreck havoc with one another and their human descendants. The action reminds me very much of the movie series, "The Mummy," with incredible high adventure. The pace is frenetic and the story lends plausibility to an number of evolution theories. We rated this book a solid four hearts.
