Love could be a theme. Maybe it's about two people who meet on this beautiful day and fall in love.
Another possible theme is redemption. The characters might have a chance to make up for past mistakes on this beautiful day. It could be that the events of the day lead them to a path of self - forgiveness and growth. The beauty of the day might symbolize the new start they are getting.
One possible theme could be appreciation of nature. Since it was a beautiful day, nature might play a big part, like the beauty of the landscape, trees, and wildlife.
One possible theme could be renewal. Just like how a new day can bring new chances. Another could be the appreciation of nature, as a beautiful day often makes people notice the beauty around them more.
The theme of fear and courage is very likely. The kidnapped character will surely experience fear, but also may find the courage within themselves to resist or outwit the kidnappers. Additionally, the novel might explore the theme of society's response to such a heinous crime. How the community reacts, whether they come together or turn a blind eye, can be an important aspect of the story.
One possible theme could be identity. As the characters go about their day in Dublin, they might be grappling with their personal identities, influenced by the city's history and culture.
Another possible theme is self - reflection. In a story about atonement, the characters would probably need to look deep within themselves, examine their actions and motives. This could lead to themes of personal growth and transformation as they come to terms with their past and strive to become better.
It might deal with themes of time and urgency. As it was written in 90 days, the idea of time running out or having to make quick decisions could be reflected in the novel's themes. Maybe there are characters who are racing against the clock in some way. Another possible theme could be creativity under pressure. Alan Watt might have explored how to be creative while having a strict time limit.
It could be about mortality. Since it has 'last day' in the title, perhaps it explores the idea of facing one's end, like coming to terms with death, regrets, or unfulfilled dreams.
One possible theme could be the acceptance of death. It might show characters coming to terms with their own mortality or the loss of loved ones. Another theme could be the transformation that death brings, not just physically but also in terms of the survivors' outlooks on life.
One possible theme could be growth. As the rangers experience their day - to - day lives, they grow both individually and in their relationship. Another theme might be sacrifice, where they have to sacrifice some personal desires for their love and their ranger duties.
Love could be a possible theme. Many stories revolve around relationships between characters, whether it's romantic love, platonic love, or love within a family.
