Anon’s gonna be an author

Invisible Man by Ellison

You could play Dark Souls.
The final boss battle is beyween two nobodies in some empty field at the literal end of time

The First Law Trilogy

I don't know about a book, but try Clannad+Clannad After Story.

The Chaos Walking trilogy

The Magus

I would say that completing the autobiography would be an accomplishment. I can't tell you how many stories I've written that never got past chapter 1

Challenger deep by Neil Shusterman

chapter 1, line one
"I existed"
The End

The Mayor of Casterbridge by Thomas Hardy. It's old and long but if you want a story where a man does everything to pull himself up from the depths and achieve success and then his past makes his life and the life of everyone else around him disintegrate anyway, this is the one for you.
