Well, popularity can be relative. In the world of military - adventure novels, it could be popular. Dale Brown has a reputation for writing engaging stories. However, compared to more general - audience bestsellers, it may not be on everyone's radar. It depends on how well it has been marketed and the specific interests of the reading public.
There are several potential themes in this story. First, there could be the theme of survival. Both the attackers and defenders are in a life - or - death situation during the storming. Second, the theme of strategy is likely present. The attackers need to plan how to breach the castle, and the defenders need to strategize how to hold it. Additionally, a theme of transformation might exist. The characters could change as a result of the intense experience of storming or defending the castle, whether it's in terms of their beliefs, skills, or relationships.
I haven't read the specific 'Storming the Castle An Original Short Story', so I can't summarize it directly. But generally, it might be about a group of people trying to storm a castle, perhaps with battles, heroism, and a series of events related to the castle - like the defenders trying to hold it and the attackers' motives and strategies.
Judy is often shown as the one who is more idealistic in fanfic. She dreams big for Zootopia and wants to make it a better place for everyone. Nick is the realist. He helps Judy see the practical side of things. Their dynamic in fanfic is really interesting as they learn from each other. Nick teaches Judy about the underbelly of Zootopia while Judy shows Nick that there is good in the world worth fighting for.
They could be characters in a science - fiction setting. Nick could be an alien from a far - off planet who crash - landed on Earth, and Macy could be a scientist who is trying to help him get back home. As they work together, they develop a bond, and the kiss could be a way of showing their connection that transcends their different origins.
I'm not very familiar with this specific work. But if it's by Dale Brown, it might be filled with his signature elements like detailed military descriptions and high - stakes action scenarios.
