There is a novel by Michel Houellebecq titled "Submission."

It is a work from 2015.
It depicts the process of France, which began accepting Islamic immigration,
becoming Islamized.
Upon its initial publication, many critics felt it went too far.
The mainstream sentiment was a sarcastic skepticism regarding whether Islam,
despite causing some trouble, could truly be an entity capable of swallowing a nation.
However,
it has gone beyond merely becoming a reality;
it has actually reached a level even more serious than that.
Perhaps,
I feel that
France
is doomed.
