Icicle

His head frozen at death, engineer and entrepreneur Braxton Thorpe awakens to existence inside an electronic matrix. Discovering the global Link System, he taps into databases and expands to become a Tensor Matrixwith access to virtually all human knowledge. He works with Daphne O’Bryan and other researchers, then is joined by an extraordinary non-human partner as he generalizes his existence from Banach Space into a Banach Manifold. Using complex tensors to extend beyond the matrix, he detects a malevolent presence in the Link system, an alien with bad intent. Braxton and Daphne must locate and reach out to this alien civilization, but what will they find, and will it be too late for mankind?
