Kafka on the Shore - Haruki Murakami

Did I do the right thing?
"You did the right thing," the boy named Crow says. "You did what was best. No one else could have done as well as you did. After all, you're the genuine article: the toughest fifteen-year-old in the world."
"But I still don't know anything about life," I protested.
"Look at the painting" he says. "And listen to the wind."
I nod.
"I know you can do it."
I nod again.
"You'd better get some sleep," the boy named Crow says. When you wake up, you'll be part of a brand-new world."
You finally fall asleep. And when you wake up, it's true.
You are part of a brand-new world.
