Love, obviously, is a major theme. It could be about different kinds of love, such as romantic love between the main characters.
Another possible theme could be discovery. The characters may be on a journey of self - discovery or discovery of each other while in this special place, the turquoise land. This could involve learning about their own emotions, values, and what they truly want in life as they interact with the land and with each other.
The 'turquoise land' in the title might suggest that nature and the environment play a role. So, themes related to the beauty of the land, and how it affects the characters' relationships or their personal growth could be present. For example, the characters might find peace or inspiration in the turquoise land.
I'm not sure about an exact similar novel off the top of my head. But novels with themes of love in natural settings might be similar. For example, 'A Walk to Remember' which also has a strong love story set in a small town with a beautiful natural backdrop.
One possible theme could be the endurance of family love in the face of change. In the tender land, things might be changing around the family, but their love remains constant. Another theme could be sacrifice within the family. Family members might sacrifice their own desires for the well - being of the whole family. And also, the theme of forgiveness might be present. In a family, there are bound to be misunderstandings, and forgiveness is key to maintaining the love.
Power is likely a theme. If it's set in a time when there were power struggles, like in a monarchy or during a revolution, Celia could be either a victim of power plays or someone who tries to gain power herself. Also, the theme of family could be prominent. Her family's legacy, secrets, and relationships might be explored in the context of the historical events.
One possible theme is scarcity. Since there's no new land, resources on the existing land would be scarce, leading to various problems.
One of the main themes could be love in a war - torn or military - influenced setting. Since it's set in the land of barefoot soldiers, it might explore how love endures or is shaped by the harsh military environment.
Another theme could be the power of friendship. Perhaps Elidoris meets different characters in the fairy land and together they face challenges, and through these experiences, the importance of friendship is emphasized. Also, the theme of good versus evil is likely. In a fairy - land setting, there are often forces of good and bad, and Elidoris may be involved in battles or struggles between these two forces.
Another theme could be the chaos that love can bring. 'Mad' often implies a lack of control, so the novel might show how love can disrupt lives, relationships, or a person's sense of self. It could also deal with the idea of forbidden love, where the passion is so strong that it goes against society's norms or expectations.
One possible theme could be the endurance of love. It might show how love can last through various challenges and difficulties over a lifetime.
Love itself is probably a major theme. It could be about different types of love such as passionate love, platonic love, or unrequited love.
One possible theme is the exploration of true identity. When love is in disguise, the characters often have to figure out who they really are and who the other person truly is.
