I don't know as I haven't read it, but usually in vampire novels, there could be a vampire leader as a main character, perhaps a human who gets caught up in their world too.
Since I haven't had the chance to read 'in the company of vampires a dark ones novel', I can only speculate. There could be a powerful vampire as a central figure, who controls or influences the other vampires in the story. Maybe there's a young and curious human who stumbles upon the vampire group and becomes an important part of the narrative. Additionally, there might be an older, wiser vampire who acts as a mentor or antagonist, depending on the plot. There could also be other supernatural beings in the 'dark ones' universe that interact with the vampires and the main characters.
Without having read the book, it's hard to say exactly. But it's common in vampire - themed novels to have a strong vampire protagonist, someone who has been a vampire for a long time and has a complex backstory. There might also be a human character who serves as the connection for the reader to the vampire world, someone who is new to the whole concept of vampires and is learning about them. And there could be other secondary vampire characters with different allegiances and goals within the 'dark ones' context.
It could be about various things. Maybe it's about the experiences of a character in the presence of vampires. It might explore the nature of vampires, their relationships, and the dark world they inhabit.
I don't know for sure as I haven't read the book. But it's likely to have vampire characters who are directly involved with the 'dark debt'. Maybe there's a strong vampire leader who has to deal with this debt on behalf of his or her clan.

I'm not sure exactly as I haven't read the specific 'Adopted by Vampires' novel. But typically, the adopted character would be a main character. There would also likely be the vampires who adopt this character, perhaps an older, more powerful vampire who acts as a sort of mentor or parental figure in the vampire family.

The main characters could also include other vampires who might not be too happy about the vampire having a pet. They could see it as a weakness or something against their vampire code. There might also be some characters who are friends or allies of the vampire - pet duo, like a wizard who helps them out when they're in trouble.
