of the Revolution. Andi becomes more interested in this story when she discovers the diary of Alexandrine Paradis, a girl who played with and watched over the prince in her youth and later became a hunted figure nicknamed The Green Man because she continued to set off fireworks all around the city for the prince to see from the tower, so he would not lose hope. As she reads through the diary, Andi almost starts to believe that Alex wants her to finish reading it instead of working on her musical DNA project on Amadé Malherbeau, a famous musician of around the same time who is known for his quirky style. During her library adventures in research and exploring around Paris, Andi meets Virgil, a taxi driver, and they begin an odd courtship of musical discourse over the phone after she accidentally leaves her iPod with him after making music together at a bar. All the while, the music she plays on her guitar and the talks she and Virgil have keep her hoping for a better future, despite her fights with her father and her emotional distress over memories the diary evokes of her own brother. After her frantic attempt to get up to the top of the Eiffel Tower to commit suicide, Virgil drags her with him down to a closed off part of the catacombs of Paris, where the bones of the thousands of dead were laid to rest centuries ago, to play at a party. When the police come in to break things up and everyone is running everywhere, Andi is suddenly transported to the 18th century and everyone thinks she is Alex. Her savior is the subject of her thesis, Malherbeau, and her confused babblings are attributed to the crack in the head she took while stumbling in the darkness of the catacombs, until she starts playing her guitar in public at the base of the tower for Louis-Charles to hear and is seriously heckled by those present. Andi carries out the rest of Alex's mission, knowing that the heart in the jar that her father is testing is indeed Louis-Charles, and that he will die in just a few nights. In exchange for his help, she gives Malherbeau her iPod, and he listens to Beethoven play music he has not finished composing yet, as well as music from more recent artists such as Radiohead.
