Great idea, execution needs works
I really like the overall story concept. I'm a bit of a nerd for these fantasy books, and in the werewolf stories a lot of them follow the same plot line. You found an original angle for this genre so that was refreshing to read into.
I think you could improve your work by being more specific with the plot. The devil is in the details. Some chapters feel like you had a general idea for how the plot needed to develop, but you rushed through the chapter, causing it to feel awkward and incomplete. Part of a good story in my opinion, is getting into the nitty gritty. For example, why was King Dante mad at Kind Sawyer for "ruining his life?"
Why does Walter hate werewolves? How did the humans lose the war? What is the history between the two kings? Are all vampires power hungry and cold like King Dante, or was Dante an exception? How do vampires find their mates? What is vampire hierarchy and culture like? A lot of stories written about werewolves give you a brief description of the general "rules" of the story world so you understand how that universe works, why things are the way they are, and since vampires are a new element here it would be nice to hear about things from their side of the aisle. These types of questions are just a few examples of elements you could add to your story to give it more depth and organic volume.
Lastly, grammar and punctuation, at least in my opinion, are SO important. They are the presentation of the meal so to speak. You have a delicious story here, but it's kind of watered down and less satisfactory because the reader has to guess the tone of the characters, the mood and the climate of the conversation, and guess what the spelling should have been. Just improving your grammar and punctuation alone would improve your story by a large margin.
Overall, this story is good and had major potential to be much better with some minor improvements. I'm only on chapter 30 so I can't wait to see how it goes!
