But the next morning, it was all still true: Chris was dead. His girlfriend Adriane, Nora's best friend, was catatonic. And Max, Nora's sweet, smart, soft-spoken Prince Charming, was gone. He was 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, no matter where 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. 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.
