Imma do a quick ranking of the books from the top of my head...
Lestats story- book 2
Akasha's story- book 3
Memnoch story- book 5
Marius story - book 8
Tarquinn story- book 9
Body thief - book 4
Louis story - book 1
Merrick story- book 7
Armand story- book 6
Books 10-13 get kinda crazy... She lost a lotta fans. Some don't really count those books.... The shit with Magnus I was talking about happens in these books. We get aliens, other shit, Lestat essentially gets leveled to a global scale in his power set. Like I don't know if y'all watch death battle or ever did hypothetical battles between fictional characters...
But Lestat in books 10-13 can keep up with Dracula, Alucard, or any other fictional vampires you can think of. It gets very sci+Fi and ridiculous towards the end.
The TV show would do well to stick to the first 10 novels if possible. But if it goes any further, I'd be genuinely surprised
