Molly McMurphy, a recent college grad whose endless curiosity fuels her consulting researcher business, has been tasked by seemingly unrelated clients to explore a series of interlocking clues within historical and literary documents and artifacts. She soon finds herself on a path to uncovering an ancient, secret group of individuals that aims to guide humanity through the ages.

As she delves into disparate details and topics ranging from MacArthur's role in the pacific, the March of the Light Brigade in Crimea, Shakespeare's home, and Sir Arthur Conan Doyle, Molly is thrust back and forth between dangerously passionate rivals within this group of guides. Are the secrets she seeks ultimately too dangerous to pursue? Or will she discover a new purpose for her life?
