At 18, Andi Alpers has lost her will to live. Her brother Truman has died, her father has deserted the family and is putting her mother in a mental hospital. In Paris, where her father is working on a project on King Louis-Charles, Andi vows to make their three-week visit a misery. But when she finds a journal that might hold the missing key to Louis-Charles history, she completely forgets about everything, including her senior thesis, and focuses instead on solving the mystery of his death.
