"Do not judge, lest ye be judged." Lily Connor stares at the photograph of the ancient scroll in front of her, barely believing what she is seeing. If the scroll is what she thinks it is, it can only be the Book of Light, a biblical document, thousands of years old, purportedly containing the transcribed words of Jesus. No one has been sure the scroll even exists - it's been kept secret for thousands of years. Now it's clear to Lily that there are people who will do anything to keep it that way.

Someone, however, wants to reveal the scroll - the question is who. And why are they sending photographs of it to Samantha Henderson, the head of the Religion Department at Tate University, where Lily is serving as interim priest? Samantha asks her to investigate, but after Samantha is attacked and Lily's apartment is burgled, the situation becomes perilous. Questions about the scroll abound, and Lily must decide if the answers are worth the price.
