The Book of Light — Michelle Blake

When Lily Connor takes a job as interim chaplain at Tate University, an all but Ivy League school just down the road from Harvard, she's happy to discover that an old friend of hers from seminary is now there as well. It's clear, however, that something is wrong with Samantha-she is thin and skittish and, more important, she looks scared. And when Samantha asks Lily for her help, it becomes something more perilous than Lily could have ever imagined.

Someone has been sending Samantha photographs, purportedly of an ancient scroll known as the Book of Light, believed to contain the transcribed words of Jesus himself. No one has ever seen it-no one even knows if it really exists. As Lily begins to investigate, it becomes dangerously clear that that is exactly the way someone wants to keep it.
