In the future, it's possible to live forever--but at what cost?
A.D. 2088. Missionary daughter Abigail Caldwell emerges from the jungle for the first time in her thirty-four years, the sole survivor of a mysterious disease that killed everyone else in her village. After receiving a curious message from her grandfather, Abby goes to America, only to discover a nation where Christianity has completely died out. Abby gives herself a new mission--to re-introduce Christian faith to America, no matter how insurmountable this seems.
But a larger threat looms. The world's leading artificial intelligence industrialist has perfected a technique for downloading the human brain into a silicon form. Brain transplants have begun, and with them comes the promise of eternal existence.
Abby and Professor Creighton Daniels, a historian troubled by the mystery of his father's sudden death, uncover a plot to force the entire planet to convert to this "transhuman" status--and forever lose all possibility of a connection with God. Together, they begin to unravel the conspiracy, attracting the attention of the powerful and devious men behind it. In a race for their lives, Abby and Creighton search for the truth while humanity's spiritual future hangs in the balance.
