Nora, Max Chris, and Adriane are all best friends, and they all (more or less) love each other. Nora is the new girl, and she is as closed as a safe. Max is the very sensitive boyfriend. Chris, oh Chris, he is the lovable peppy person that everyone wants to be around. Finally there's Adriane, the ''pep in your step'' cheerleader type who couldn't be mean even if she wanted to.
 Nora just started at the ''new'' prep school, and she is really loving it! Her friends sucked her into the world of deciphering Latin letters. At first she thought that it was stupid, and that it meant nothing, but she was wrong. Elizabeth, the 200 year old dead girl, wrote these heartfelt letters long ago to her brother, informing him about all that is going on where she was living. Of course, Nora thought that these particular letters were useless, but no that was far from the truth, these letters held that secrets to the Lumen Dei.
 The old paranoid professor, The Hoff, always told the group that ''The Book,'' would change history. The Hoff couldn't have been more right.''The Book,'' didn't change the modern world, but it really did change history, and how we look at entirely.
