Brandon Sanderson Grim Dark Book Review

It was Mistborn in this, so this unpublished book. Can you even imagine a Brandon Sanderson grim dark book? That's like no one's happy and everyone's mean all the time. He went there and he falls in with a crowd of nice people who treat him well. And he doesn't know what to do with that and has a character arc to where he goes back and defeats his father. "I kidnapped a Joe Abercrombie character and subjected him to nice people until he had a character arc"
