But behind its walls, Americaa (TM)s top scientists work around the clock to attain the holy grail of the twenty-first century - a supercomputer that surpasses the power of the human mind. Appointed by the president as ethicist to Project Trinity, Dr. David Tennant finds himself in a pressure cooker of groundbreaking science and colossal ambition. When his friend and fellow scientist is murdered, David discovers that the genius who runs Project Trinity was responsible and that his own life is in danger.

Pursued across the globe by ruthless National Security Agency operatives, David and Rachel struggle to piece together the truth behind Project Trinity and the enormous power it could unleash upon the world. As constant danger deepens their intimacy, Rachel realizes the key to Trinity lies buried in Davida (TM)s disturbed mind. But Trinitya (TM)s clock is ticking . . . Mankind is being held hostage by a machine that cannot be destroyed. Its only hope - a terrifying chess game between David and the Trinity computer, with the cities of the world as pawns. But what are the rules? How human is the machine? Can one man and woman change the course of history? Mana (TM)s future hangs in the balance, and the price of failure is extinction.
