"The past is obdurate."

This concept is narritively explored in Stephen King's "11/22/63" if anyone finds this interesting.

The novel is an entertaining read and the audiobook available on the Libby app (requires a local library card here in the US) is high quality.

There's also a James Franco mini series based on the book, which is alright albeit a bit slow moving.
