The Book of Blood and Shadow — Robin Wasserman

One night. One body, broken in a pool of blood. One killer, lost in the shadows. One girl, left behind -- left alone, to face the consequences. To find the truth. To avenge the dead.

Nora's best friend, Chris, is dead. His girlfriend, Adriane, is catatonic. And Max, Nora's sweet, smart, soft-spoken Prince Charming, is gone. He is also -- according to the police, according to her parents, according to everyone -- a murderer.

Desperate to prove his innocence, Nora follows the trail of blood, wherever it leads. It ultimately brings her to the ancient streets of Prague, where she is drawn into a dark web of secret societies and shadowy conspirators, all driven by a mad desire to possess something that might not even exist. For buried in a centuries-old manuscript is the secret to ultimate knowledge and communion with the divine. It is said that he who controls the Lumen Dei controls the world -- and unbeknownst to her, Nora now holds the crucial key to unlocking its secrets. Her night of blood is just one piece in a puzzle that spans continents and centuries. Solving it may be the only way she can save her own life.
