The Bear and the Nightingale by Katherine Arden

Masterful storytelling! A splendid mix of fantasy and old Russian fairy tales and a must for readers who enjoy being scared just a little to get the point across. Vasilisa is born of mixed blood - peasant and noble and has grown up with the old ways but will be introduced to the new wave of Christianity that will find its way into her village. She is as wild as her brothers but has the sight and leaves offerings for the various creatures that protect the village and surrounding wood. With this sight she must also pay the price of being branded a witch, a demon child and the responsibility of saving the village from the Bear who brings his horde of vampires and demons. There is another who only a few can see, the Bear's brother, who will help Vasilisa but will demand much of her as well. This is the classic battle between good and evil, between the old ways and the new and between the pure of heart
and those who want glory above all else.
