Well, from the title 'one foot in the grave a night huntress novel', it could be a story that combines elements of mystery and danger. The 'night huntress' part makes me think of a female protagonist who hunts at night. It could be that she's involved in a world full of supernatural beings or criminals. And the 'one foot in the grave' might suggest that she constantly puts her life on the line in her pursuits. Maybe she has a mission that is so dangerous that it's like she's always close to death.
Given the title, the main character is most probably the night huntress. We can assume that she is a central figure in the story. She might be a complex character with her own set of motives and goals. It's possible that she's on a quest for revenge or justice, which is why she's constantly in dangerous situations that put her 'one foot in the grave'. She could be a loner or part of a group, but whatever the case, she's the focus of the narrative in this novel.
The 'Foot in the Grave Vampire Novel' might center around a vampire that has some connection to the concept of mortality, even though vampires are typically immortal. Maybe it's a story where the vampire is facing a threat that makes it feel like it's nearing the end, like an ancient curse or a powerful enemy. It could also explore themes of redemption or a final reckoning for the vampire's past deeds.
I'm not sure as I haven't read the novel. But it could have a vampire as a main character, perhaps an old and jaded one given the 'foot in the grave' part of the title. There might also be a human character who gets involved with the vampire, like a vampire hunter or someone who is unknowingly drawn to the vampire's world.
The main theme is cultural clash and reconciliation. It shows how different cultures, in this case French and Indian, can initially collide but eventually find common ground and mutual respect.
