Plot summary.
When she is five years old, Lili watches her mother, Roxanna the Angel, throw herself off the balcony of their house on the Avenue of Faith.

The only witness to Roxanna's disappearance, Lili will spend the next thirteen years looking for her mother, wondering if she is still alive and why she left.
