The main characters are the so - called 'devil' character, who is often a complex and brooding figure, and the female lead. Their personalities clash and attract at the same time, which makes for an interesting dynamic.
Evie is one of the main characters in 'Devil in Winter'. She's a complex character who has been through a lot in her life. Sebastian, on the other hand, is a charming but rather wild man. Their relationship forms the core of the story, and as the plot progresses, we see how they both grow and change as individuals and as a couple. There are also some secondary characters that add to the richness of the story, like Evie's family members who play important roles in her life and her relationship with Sebastian.
The main characters could include a strong - willed female lead. In historical novels, female characters sometimes have to navigate through male - dominated societies. And then there might be a male character who is either the 'devil' or is associated with him. For example, he could be a rival or a partner in some sort of scheme. And there are usually supporting characters like servants or family members who add to the complexity of the story.
One key theme is redemption. The 'devil' character often has a past filled with misdeeds and through the course of the story, he or she seeks redemption, usually through love. Another theme is transformation. The relationship in the novel changes the characters, making them better versions of themselves. And of course, love is a central theme, with the relationship between the main characters being the driving force of the story.
There might be a female character who is either a commoner with a special gift or a noble from another land. She would be the love interest of the king. There could also be side characters like loyal knights or cunning advisers who play important roles in the story, either helping or hindering the relationship between the main characters.
The main characters might include a detective if it's a mystery set in winter. He or she could be a jaded but brilliant investigator who has to deal with the cold and the secrets that the winter seems to hide. There could also be a group of friends who find themselves in a dangerous situation during winter, like being trapped in a remote cabin with a murderer on the loose.
In 'the winter soldier novel', the most prominent character is the Winter Soldier. However, other important characters may include those who are trying to help him break free from Hydra's control. There could be some fellow soldiers or agents who discover his true nature and decide to assist him. Also, antagonists within Hydra who will do anything to keep him under their control are likely to be part of the main characters in the story.
Since I haven't delved into 'the Winter King' novel, it's difficult to name the exact main characters. However, based on typical fantasy or historical fiction themes, apart from the eponymous Winter King, there could be a brave knight who is loyal to the king. There might also be a wise old wizard or a cunning court jester who, in his own way, influences the events in the kingdom. And of course, there could be an enemy leader who is constantly plotting against the Winter King.
Since I'm not familiar with 'the winter girl novel', it's difficult to name the main characters precisely. But based on the title, the central character is the winter girl. She may have a best friend who stands by her side throughout the events of the story. There could also be an older person, perhaps a grandparent or an old family friend, who imparts wisdom to her during the winter. Additionally, there might be a character who is a bit of an outcast in the story, and the winter girl forms an unexpected bond with this person, which becomes a crucial part of the plot.
Not having read it, I can only guess. There might be a protagonist who is a struggling artist or a lonely traveler. And perhaps there are supporting characters like a kind old man or woman who help the main character, the 'star' in this wintry story, on their journey.
I don't know the exact main characters as I haven't read it. But they could be ordinary people like a hunter, a mother, or a young adventurer.
