"When we all fall asleep where do we go?" Unfortunately for Bianca Brooks, Billie Eilish's question isn't a deep secret to ponder, but a painful reality. Torn between two worlds, Bianca's struggle to graduate high school morphes into a frantic effort to survive.

Dryads are known for their soul-sucking habit, and have terrorized humans since the beginning of time. Every man has feared them, except Hunters of Magic, who seek their head for a bounty. Nies is a young Dryad, who only wants one thing: to be human. She dares to leave her sanctity of the forest to venture out into the world and find the means of creating a child for herself. In order to achieve this goal, she must find a worthy human to surrogate this child. When she encounters Jolette, a human with a bad reputation, Nies agrees to help her escape to Kazo City, a land who knows not of Jolette's name, if the human herself protected Nies until she found a bride. Along the way, these two meet exotic creatures and make sketchy companions that accompany them on their journey to this sacred city. But Nies has a secret-her body is hungry for a soul. And Jolette's looks like the perfect meal.
