The main character in the 'vampire loses his grave dirt novel' is the vampire. However, there may be other important characters as well. There could be a female vampire who is in love with the main vampire and she might play a crucial role in his journey to deal with the loss of the grave dirt. Also, there could be a vampire slayer who initially thinks the weakened vampire is an easy target but then realizes there's more to the situation and ends up having a complex relationship with the vampire, either becoming an ally or still remaining an adversary in a different way.
I'm not sure specifically about this novel as it's not a widely known mainstream one. But generally, perhaps the vampire losing his grave dirt could lead to him losing his connection to the place that gives him a sense of safety and power. Maybe he has to search for a new source of strength or face new threats without the protection of his grave dirt.
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.
It could be Voldemort. Voldemort might use Harry's love as a weapon against him. He could either kill her or turn her against Harry. Another possibility is Draco Malfoy. Maybe Draco tricks Harry's love into thinking he's a better choice. Or it could be a new, unknown dark wizard who targets Harry through his love.
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.
