I'm not entirely sure as I haven't read it specifically. But generally, a light novel might be about the story of a 'Secret Lady', perhaps her adventures, her hidden identity, or her relationships in a fictional world.
Love is likely to be a main theme. Often in such novels, the relationships between characters, especially the romantic ones, are central. Another could be secrecy itself, as the title implies that there are secrets held by the lady in the story.
Sure. 'Gone with the Wind' has some similarities. Scarlett O'Hara has many aspects of her personality and past that are like secrets she holds within. Also, 'The Scarlet Letter' where Hester Prynne has a great secret that shapes her life and the way society views her. Additionally, 'Middlemarch' which has multiple characters with their own unspoken desires and secrets much like in 'Secret Lady Novel'.
One of the main themes is deception. Lady Audley has many secrets and she uses deception to hide them from others. Another theme could be the position of women in society at that time. Lady Audley's actions are, in a way, a reaction to the limited options available to women. Also, the idea of appearance vs. reality is prominent as her outward charm hides her dark secrets.
Lady Audley is obviously one of the main characters. She is the one with the big secret. Then there's Robert Audley, who plays a crucial role in uncovering her secrets. Also, George Talboys, whose relationship with Lady Audley is an important part of the story.
The novels from Wild Rose Press in this genre often have rich historical settings, complex characters, and hidden secrets that drive the plot. They usually focus on the emotional journey of the lady protagonist.
The following are some of the recommended completed novels about the reborn Di daughter: " The Rebirth of the Di Daughter "," The Rebirth of the Di Daughter Peerless "," The Original Di Daughter "," The Rebirth of the Di Daughter Betrothed Elsewhere "," The Rebirth of the Beautiful Di Daughter "," The Rebirth of the Di Daughter City-Toppling "," The Rebirth of the Medical Di Daughter "," The Rebirth of the Marquis's Di Daughter "," Rebirth after Abandoning: The Revenge of the Di Daughter, The Rebirth of the Evil Phoenix Controlling the Husband, The Rebirth of the General Poison, The Rebirth of the Di Daughter Fierce Concubine, The Rebirth of the Parting Crying in Front of the Palace's Grave, The Emperor's Beauty, The Eldest Daughter of the Di, She Is Beautiful and Savage, The Rebirth of the Di Daughter in Charge of the Family, etc. These novels covered different styles and plots, suitable for readers who liked the theme of reborn daughters.
I'm not sure specifically as I've not heard of a novel named just 'secret a secret novel'. It could be about a hidden mystery or a secret that's central to the plot.
