Echo of the North. Ruth Meyer D.

Her name is an echo. She is a game girl whose beauty was taken away by a ruthless predator. But no hardships are able to harden the girl. For the sake of saving her father, she is ready to sacrifice freedom, becoming a captive of the very white wolf who once attacked her. Now the echo lives in the forest, in a fascinated house, becoming his guardian. She collects lunar and sunlight, feeds animals and monitors the mirror library. That's just the curse of this unusual place is stronger, and the secret of the wolf is much darker than the echo could imagine. Now the girl has to meet with ancient forces that control the forest, and take advantage of the strongest magic that is available to the human heart.
