Can someone give me a general overview/pitch of The Queen of the Damned? I don’t mind spoilers.

I absolutely loved IWTV & The Vampire Lestat (except those song lyrics, lol) but I hit a wall with TQOTD. What do you like about it? If you had to summarize it, what’s is about? How’s it formatted? Give me your pitch! I need a different perspective. I want to like it!!
