Quote 1, from the series Magnus Chase and the Gods of Asgard:

My name is Magnus Chase. I'm sixteen years old. This is the story of his my life went downhill after I got myself killed.

My day started out normal enough. I was sleeping on the sidewalk under a bridge in the Public Garden when a guy kicked me awake and said, "They're after you."
