After more than two centuries imprisoned by her father, Ash escapes Lucian's clutches—taking with her three young girls he also held captive. On the run, Ash must keep them safe, but doesn't have a plan, until a pull from deep within her soul draws her home—the one place she has longed for.

Woodlight, home to witches, druids, and the Tree of Knowledge, welcomes her back. But peace is short-lived. Ash is more than a daughter of Endor. More than a tree guardian. She is the anchor that holds the balance and the only one who can defeat Lucian.

Yet after centuries in chains, the last thing Ash wants is to be bound again—by duty, destiny, or even the stirrings of her own heart. As she battles life in an unfamiliar world, and the lingering influence Lucian still holds over her, Ash must learn to trust the people of Woodlight, including Bran, the ancient druid whose quiet strength can help her heal.

But when Lucian tricks her into giving him the ancient Book of Endor, Ash sets into motion a final battle that will decide the fate of the tree, the world—and her soul.
