Survival is likely to be a big theme. In a post - apocalyptic world, the characters, including the empress, would need to fight for their lives.
Power struggle could be another theme. As an empress in the last days, she would probably face challenges from others who also want power and control over the scarce resources. Also, the theme of human nature is often explored in such novels. In difficult times, people may show their best and worst sides, and the empress would have to deal with all kinds of people.
The theme of rebuilding could be present. After the apocalypse, the empress might be trying to build a new society or order. This could involve making difficult decisions about who to trust, how to distribute resources, and what kind of values to promote. There could also be a theme of hope, as the empress might be a symbol of hope for the survivors, leading them towards a better future in a world full of despair.
One possible theme could be change. May is often a time of transition in nature, so the last days of May might symbolize a shift. Another theme could be endings, as it's the end of the month.
It could be about time. Since it has 'Twelve Days' in the title, time might be a crucial factor, perhaps a countdown or a period within which certain events need to be completed.
Another theme might be growth. Over 8 days, a character could grow in terms of their knowledge, skills, or emotional maturity. For example, if it's a story about a student on a study trip for 8 days, they might learn a great deal about a new subject or culture and grow as a result. Also, the theme of discovery is quite likely. It could be the discovery of a new place, a new friendship, or a hidden aspect of oneself within those 8 days.
A third theme might be relationship building. In 100 days, a person could focus on improving their relationships with family or friends. They could plan special outings, have heart - to - heart conversations, and by the end of the 100 days, strengthen those bonds significantly.
One possible theme could be the power of stories. Since it's about the last storyteller, it may show how stories can influence people, shape cultures, and even change the course of events.
Another theme could be the passage of time. The story could show how time changes the characters, their relationships, and their environment. For example, how memories fade or how people grow and change over the years, which can be a very poignant and engaging theme in a novel.
One possible theme could be loneliness. Rainy days often evoke a sense of isolation, and if the novel is named 'My Rainy Days Novel', it might explore the feeling of being alone. Another theme could be renewal. Just as rain can wash away and start anew, the story might deal with characters starting over in some way.
One possible theme could be self - discovery. The main character might use the seven days in Sydney to learn more about themselves. Another theme could be adventure, as they explore the city.
Since I haven't read it, it could be about friendship. Many light novels explore the deep bonds between characters, so it might be a theme in 'Five Days Light Novel'.
One possible theme could be time. Since it's set over twenty days, the passage of time and how it affects the characters and events would be significant. Another could be place, as it's in Turin, so themes related to the city's identity, its unique features, etc. might be explored.
