A secret room has been discovered in the chapel of the Bowery Mission. And what’s hidden inside could change the world as we know it.

When New Yorker Tom Bohannon uncovers an ancient cipher containing a dead language that has been lost in the sands of time, he doesn’t fully comprehend the danger that’s about to unfold. Though Tom and his team of ragtag scientists and historians want to decode the ancient text, there are others who don’t want the cipher revealed. And they are prepared to kill to keep it hidden.

From a market in 19th century Alexandria to an apartment in present-day New York to the tunnels beneath Jerusalem, the secret of the cipher has spanned the globe --- and threatened the lives of everyone in its path. Will Tom be next?
