Reception
The Winternight trilogy has received positive reviews.

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."
