The Girl in the Tower and The Winter of the Witch conclude the Winternight trilogy and the story of Vasya, a young girl growing up in a remote village in Northern Russia on the edge of the wilderness.

In The Girl in the Tower, Vasilisa faces an impossible choice. Driven from her home by frightened villagers, she has only two options left: marriage or the convent. She cannot bring herself to accept either fate and instead chooses adventure, dressing herself as a boy and setting off astride her magnificent stallion, Solovey.

In The Winter of the Witch, Moscow has been struck by disaster. Its people are searching for answers—and for someone to blame. Vasya finds herself alone, beset on all sides. The Grand Prince is in a rage, choosing allies that will lead him on a path to war and ruin. A wicked demon returns, stronger than ever and determined to spread chaos. Caught at the center of the conflict is Vasya, who finds the fate of two worlds resting on her shoulders.
