I have a complex narrative structure, utilizing multiple perspectives and timelines, with themes of trauma and the lasting impact of war on individuals and families. One key symbol is a particular flower, and the setting includes both Europe and Vietnam.

1. The book involves a character named 'Lily' and another named 'Clara'.
2. It shifts between the early 20th century, World War II, and the Vietnam War.
3. The main characters are connected through a series of photographs and hidden letters.
4. The novel explores the ripple effects of secrets and the challenges of reconciliation.
