Dreams of Flesh and Sand — W.T. Quick

Double En, the most powerful corporation ever created, and its founders, Nakamura and Norton, are two of the most brilliant minds in history. But now they have launched a private war against each other and winner takes all. While Norton is hidden deep inside the heart of the Double En's mainframe, Nakamura is busy hiring the very best in computer warfare -- that's Iceberg Berg, master of security systems. No one can penetrate a barrier he has created, except for one woman, his ex-wife, Icebreaker Calley. No wall has ever been barred to her. Together again, they face the impossible task of separating Norton from his beloved matrix before the man becomes the computer and the computer becomes more powerful than anything humanity has ever seen.
