"“Where does Norga take you, then? Perhaps I could rescue you, somehow.”
He shook his head. “That is impossible. Norga’s palace can only be found east of the sun, and west of the moon.”
“But that’s . . .” She lifted a startled face to his.
“Yes. That’s no place at all.”
“I do not care. I will find a way.”
Mistress of the Wind - Michelle Diener
