One of my favorite books which I'll never shut up about is an oldie but a goodie: The War of the Worlds by H.G. Wells. A horrifying look at Earth in the throes of an extraterrestrial invasion, with humanity's extinction almost certainly assured, causing us to rethink our place in the universe and in the grand scheme of things.
Also, super cool Martians and their fighting machines!
There have been many adaptations of this story over the years, the best of which, in my opinion, is the 1978 album Jeff Wayne's Musical Version of The War of the Worlds. Very faithful to the spirit of the original novel, also full of earworms that live rent-free in my head 24/7.
