The theme of survival could also be prominent. In a world where werewolves exist, there might be threats from other werewolves, humans who are aware of their existence and want to harm them, or other supernatural beings. Grayson and Belle would have to fight for their survival, both physically and in terms of maintaining their way of life. This struggle for survival could drive the plot of the novel.
Love is likely a main theme. It often is in novels that feature two main characters like Belle and Grayson. Their relationship would probably be at the center, exploring different aspects of love such as attraction, affection, and commitment.
