I absolutely loved The Bear and the Nightingale. Katherine Arden has crafted a beautiful tale of wildness, beauty, and fantasy. It’s the story of Vasilisa–called Vasya by those who love her–and her family’s trials and triumphs in a world that doesn’t always believe in the mystical. In the wilds of Russia, far from the civilized world of Moscow, Vasilisa and her siblings grow up believing in Morozko–the not-always-nice Frost–and other household and wilderness beings such as the domovoi and the rusalka. It chronicles the life of Vasilisa as she grows and discovers how to reconcile her old beliefs with new ones that make their way to her household.
The Bear and the Nightingale opens with a Russian folktale, that of Morozko and the maiden. It sets up the story quite well, as there are parallels to this folktale throughout The Bear and the Nightingale. While I would say that is the main folktale that is threaded throughout the book, Arden has included more of the mythology and stories of the region to create a rich cultural setting in addition to a rich physical setting. And it wasn’t mentioned just to have “culture.” The beliefs of the North–which is, according to those who live in the cities, obsolete and incorrect–are consistently in the narrative. As Vasilisa grows, Arden introduces more of the mythology as she learns about it through exploring her world. It was a natural way of storytelling and of growing the world contained in the book.
