The forest has never felt this wrong.

When Ella Flare steps into a withered, dying wood, the very air warns her of something unnatural. Deep within, she finds a hidden ballroom where couples are trapped in an endless, enchanted waltz—among them, her own parents.

With Wolfie at her side and her father's axe in hand, Ella enters the illusory world of the Sleeping Court. But the deeper she goes, the more the magic tangles around them, and the more she wonders about Wolfie's future.

Time is running out. To save her family and the other lost souls, Ella must break the spell before the dance claims her too.
