Well, in 'Survive as the Hero Wife' novel, it could involve the heroine's journey in a world full of heroic deeds and perils. She may need to use her wits and strength to survive. Maybe she has to navigate through political intrigue in a world where heroes are revered. Or she could be in a situation where she has to protect herself and the hero from unseen threats that come with his heroic status.
As we don't have much information about the 'Survive as the Hero Wife' novel, it's difficult to determine all the main characters. However, it's obvious that the wife is a central figure. There might also be other characters like the hero's friends or allies who play important roles. Maybe there are villains in the story who try to harm the hero or his wife, and they would also be significant characters.
I'm not sure exactly as I haven't read it. But generally, it might be about a woman who has to face various challenges while being the wife of a hero. It could involve things like dealing with the hero's dangerous lifestyle, his enemies perhaps trying to get to her to harm the hero, or just the normal relationship issues but in a world where her husband is a heroic figure.
I'm not familiar with the specific novel, but in a story like this, the hero and his wife are likely to be central. The hero is probably a brave and well - known figure, and his wife is the one who has to navigate the world around his heroism. There could also be antagonists, perhaps people jealous of the hero or those with evil intentions who target the couple. And then there may be allies of the hero, who also interact with his wife and contribute to the overall plot.
Another theme is identity. She is often defined by her relationship to the hero at first, but then has to find her own identity within the story. For example, in many such novels, she starts as just 'the hero's wife' but then becomes a strong individual with her own story arc. Also, there is the theme of loyalty. She has to show loyalty to the hero, but also has to figure out when that loyalty might be tested and how to handle it. This can be in the face of external threats or internal conflicts within the relationship.
