Following a biking accident, Boston grad student Zack Kashian lapses into a coma. When he wakes up on Easter, months later, muttering the Lord's Prayer in the original Aramaic, the media quickly anoints him the "Miracle Man."

Zack's revival catches the attention of a small team of neuroscientists secretly researching near-death experiences. Their objective: to determine if there is anything to the reports of floating down tunnels into celestial light and meeting spiritual beings. Is this evidence of the afterlife? Or is it just neurobiology, as Sarah Wyman, one of the young researchers, suspects?

Zack's experiences are anything but heavenly. While he and Sarah struggle to understand his horrific out-of-body experiences, sinister forces have taken an interest in them. Forces to whom near-death experiences are utter blasphemy deceptions created by Satan himself and who, in the name of God, will stop at nothing to terminate the project and all involved."
