It sounds like all your books are sequels. Oh my, I misled you. They're not really sequels in the strictest sense of the word. But they're connected in some way, with recurring characters, or objects from one book that show up to play a role in the next. Oh, all kinds of places.
Some writers really take that to heart and never try to write about anything unfamiliar.
I say that's nonsense. That said, I think you can see how the entire world can be a swirl of story ideas. Life is exciting. There are conflicts and irony and humour all around us. It's great fun.
