I'm not sure if it's extremely popular. It might be well - known within certain circles of readers who are into that genre, but it may not have mainstream popularity.
I'm not sure specifically as I haven't read it. But generally, a novel with such a title might be about a powerful figure in the underworld world. It could involve things like power struggles, crime empires, and the character's journey to become or maintain his status as the 'king' in that dark and dangerous realm.
Another option is to check with your local library. Libraries have a diverse selection of books. They can either have it on their shelves or they might be able to order it from another library through inter - library loan systems. So, it's definitely worth giving your local library a try.
Well, the 'king of the underworld' concept has been explored in many fictional works. In some tales, he is not just a criminal but also has a certain code of ethics within his own world. He might protect those in his territory in exchange for loyalty. His story could involve a long journey of building his underworld kingdom, facing challenges from law enforcement agencies, and dealing with internal disputes within his criminal organization. It's a complex character type that can be molded in many different ways in different stories.
I'm not sure which specific 'King of the Underworld' story you're referring to. There are many different interpretations in various mythologies and fictional works. For example, in Greek mythology, Hades is often considered a king of the underworld. His story involves his abduction of Persephone and his rule over the dead. But if it's a modern fictional 'King of the Underworld', more context is needed.
Power is a main element. The 'king of the underworld' has to have a great deal of power to control his domain. Another is loyalty. He demands loyalty from his followers.
Again, depending on the context. In Greek myth, one main event was Hades' deal with Zeus regarding the division of the cosmos, which led to him becoming the ruler of the underworld. Also, his taking of Persephone was a huge event that had consequences for the seasons on Earth.
