I'm reaching out to see if the community can help identify a book (or series of books) from my childhood in the 80s.
To the best of my recollection, the stories were about a family of vampires - but they may have been nonspecific "monsters."
I believe one among them was considered very handsome because he looked almost human (speculation: implying the others had varying levels of disfigurement from their vampirism/monster-ness)
Wracking my brain for further plot details, the only strand I can eke out is possibly that the family of vampires wanted to take over the world, but one among them had misgivings; that's bordering on mistaken memory, though, I'm running on empty for more plot detail.
I remember thinking for the longest time that it was one of Roald Dahl's works; the tone of the story and artwork felt very Dahl-esque, but his bibliography reveals the work I'm referencing is not his. The work was aimed at the 6 - 10 age group, not really up to YA. I'm also fairly sure this was a series of books, not just one. The artwork was sporadic, i.e. it wasn't a-picture-a-page type of story.
I read the book in English, which I'm almost sure was it original language of publication; very likely it was by an English author. I doubt the work was from before the 70s, and it would not have been from the 90s.
I've trawled the internet searching for various permutations and combinations of vampire/family/80s/children's book to no avail. I didn't think this work was that obscure, but it apparently is; I'm hoping someone out there might have ideas what this may be.
