Harry Potter wrote itself

​Harry Potter wrote itself.
Surely, most of the HP universe floated in the ether above the UK, just waiting to be channelled in the ink that bled on those pages. I already had an inkling that there could be some "geomagic" at play after repeated visits to London; but after staying in Edinburgh this past week, I feel it's true.
I am bewitched. And I cannot stop thinking about how much we owe to the places we live in, we visit, we love, and also the ones we hate, the ones we run away from, and ultimately the ones we create in our minds.
A writer has many sources of influence, a sort of unique "nature and culture" brew that will set them apart. It's obvious when they write about historical events or place their fictional events in a specific historical context, but much less when what they write seems disconnected from our reality.
I am convinced however that places have magical powers and some are so strong that you can only give in and write.
It also gives me pause. Are we then limited as well by some places? Is there such a thing as a "geocurse", when one can only write about a limited aspect of the world just because of where they happen to be born or to live?
So, tell me, do you think it's true, that places hold magic for a writer?
What book do you feel could not have been written by someone from any other background or who lived in another place other than the author who wrote it?
