Well, without having read the 'kings ransom novel', we can only guess. It could be about a fictional king in a made - up world. The ransom might be not just in terms of gold or jewels but also something more abstract like a sacrifice or a great task. The story might follow the characters who are involved in the demand for the ransom, the king who has to deal with it, and the events that unfold as a result. It could also be a story of heroism, where someone tries to prevent the payment of the ransom or tries to rescue the king without paying it.
