In a secret government lab, America's top scientists work on Trinity — a supercomputer that could surpass the power of the human mind. As the project's ethicist, Dr. David Tennant works in a firestorm of limitless science and ruthless ambition. After a fellow scientist is murdered, David uncovers who the killer is. Desperate, he turns to Rachel Weiss, the psychiatrist probing the nightmares that have plagued him since joining the project, and both are forced to flee for their lives.

Pursued around the globe, David and Rachel piece together the truth behind Project Trinity, and the apocalyptic power it possesses. But Trinity's countdown has already begun, and humanity is now held hostage by a form of life that cannot be destroyed. The only hope for survival lies in the shocking connection that exists between Trinity and David's tortured mind. Mankind's future hangs in the balance — and the price of failure is extinction.
