His head frozen at death, engineer and entrepreneur Braxton Thorpe awakens a century later to existence inside an electronic matrix. He discovers the GlobalNet served by ServerSky, and taps into databases and expands to become a Tensor Matrix with access to virtually all human knowledge. He works with Daphne O'Bryan and other researchers, then is joined by an extraordinary non-human partner, the Oort, as he generalizes his existence from Banach Space into a Banach Manifold. Using complex tensors to extend beyond the matrix, he discovers a malevolent threat to the entire Solar System, marauding Aliens with bad intent. Braxton and Daphne, assisted by the Oort, must build a defense against this advanced alien civilization, but can they do this in time, or will it be too late for mankind?.
