Reception
The Winternight trilogy has received positive reviews. Critics from Publishers Weekly praised The Bear and the Nightingale, stating "Arden’s debut is an earthy, beautifully written love letter to Russian folklore, with an irresistible heroine who wants only to be free of the bonds placed on her gender and claim her own fate in 14th-century Russia." Kirkus stated, "Arden has shaped a world that neatly straddles the seen and the unseen, where readers will hear echoes of stories from childhood while recognizing the imagination that has transformed old material into something fresh", in a starred review. Everdeen Mason of The Washington Post, said "Arden’s debut novel has the cadence of a beautiful fairy tale but is darker and more lyrical."

The Bear and the Nightingale was named Amazon's "Best Book of January 2017".
