The unusual is presented in this book with real life experiences, integrated with facts, fiction, and modern scientific concepts to form this story of The Doppelganger Brane. The narrative extends from the inner space of the deep ocean with its undersea volcanic activity to the outer space of multiple universes and wormholes. Mysterious conditions enshroud the curious, but technically oriented Reinhardt family in a potentially hazardous relationship with unknowns as well as the nefarious human elements. Suddenly the invisible nano-world must be recognized as the family companion while the intangible, counterintuitive existence of other invisible worlds must be accepted. Fighting to honor their sense of responsibility to maintain newfound secrets, the Reinhardts find themselves making unforeseen sacrifices defending the interests of entities borne of a quantum world. As suggested by their newfound unkowns, the existing world civilization appears to be an immature place with multiple human-earthling shortcomings. One example is the E'lan, a nefarious cabal that the family has to fight to prevent their unsavory possession of highly advanced technology. Fortunately, some much needed assistance is provided by U,S, Navy who also has a brush with the E'lan trying to steal the Navy's secret Pod technology.
