Gretel loves her brother, Hansel, but lately she barely recognizes him. It's been months since that terrible day in the cottage, when she found her brother in grave danger and had to kill the witch. Her life has changed completely since then—she now lives in a big castle with Hansel and their father, forced to wear corsets and dance with boring, old men at balls.

One day, while wandering in the woods next to their new property, Gretel comes across a community of witches. But what she sees is nothing like the stories she's heard. These witches are healers, helping those in need.

Gretel must dig deep to find the truth of what really happened that day in the cottage. And when she's forced to confront everything she knows about her family and the world around her, she must decide where her true alliances lay.
