I'm not sure specifically what Clayton's children's stories are about without more context. It could be about their adventures, their relationships with family and friends, or lessons they learn in life.
Well, it could have themes like family values. In Clayton's children stories, perhaps there are tales about how families support one another through difficult times. Also, discovery might be a theme, as the young characters discover new things about themselves and the world around them.
Since I don't know the details of these stories, I can't say for sure who the main characters are. But I assume Clayton's children themselves would be the main characters.
I think it does have a happy ending. Clayton overcomes the challenges and gets what he was striving for. But it's not a conventional happy ending; it has its own twists and turns.
Clayton novels usually have strong character development. Take 'A Connecticut Yankee in King Arthur's Court'. The main character from modern times is thrust into the Arthurian era. Through his experiences, we see his growth, his struggle to adapt, and his attempts to introduce modern ideas into a medieval world. His character arc is complex and interesting, which is a common trait in Clayton novels.
There were two cultivation novels about his wife's betrayal that he could recommend. The first book was " Cultivation, Starting from My Wife Betraying Me ", written by Mr. You. The main characters were Li Xuan and Qin Yanran. The story described how Li Xuan obtained the inheritance of cultivation after his wife betrayed him. He began his path of cultivation, pursuing beautiful women and enjoying life. The second book was " Cultivation in a Different World ". The main character's name was Xia Yu, and the woman who betrayed him was called Tang Xuan. He later became an immortal cultivator and cultivated the sword path and the immortal path. These two novels belong to the fantasy sci-fi genre. If you are interested in the story of your wife's betrayal, you can try reading these two novels.
I'm not sure exactly how many are on the list you mentioned. There are quite a few, with Edgar Rice Burroughs writing many Tarzan novels over the years.
The meaning could be about a repetitive or common situation. It might refer to the recurrence of certain events, emotions, or patterns in life that are all too familiar, like a 'same old story' we've heard or experienced many times before.
