Writing a novel was a task that required patience and creativity. It required a deep understanding of the story, character creation, plot development, and so on. If you have enough inspiration and ideas, you can try to write your own novel. But writing is a process that requires constant practice and improvement, and constant learning and practice.
At the same time, reading novels was also a very beneficial habit. It could expand one's horizons and imagination and help one better understand the plot and characters. By reading various types of novels, one could improve their writing skills and creativity to write better novels.
I'm not sure as I haven't read the novel specifically. But they could be characters who are strong - willed and self - reliant, given the title's implications.
The main theme might be about self - preservation and the fear of being left behind. It could show that the characters in the novel prefer to take the initiative to abandon rather than passively endure being abandoned, which might be related to issues of control and self - worth.
It could be due to a series of unexpected events and circumstances that led to your character's transformation. Maybe there was a prophecy or a hidden heritage.
