I need a fall read and can’t find a book that meets what I want

need help 🥺

I want to read a book that gives the same vibes as the song forever young by alphaville. I crave it for my fall read but I can’t find something that makes me feel it. I want it to be someone who can’t die and enjoys the immortality until they realize how crappy it is – if that makes sense.
Or
I want a book rec with Armageddon (movie) vibes. I need an AJ and grace romance with tragedy and suspense/ thriller. Thank you
