In the conclusion of this bestselling fantasy series a nonbinary knight-in-training, a reluctant crown prince, a fierce young witch, and her resilient twin brother must fight for the heart of their kingdom against tyranny, once and for all.

Helston and its champions have been torn apart by war. Finally reunited after being scattered across the realm fighting personal battles, Callie, Elowen, Edwyn and Willow must prepare to step into the roles they've been training for: Champion, Witch, Knight and King.

Even if it feels like their best will never be enough to conquer the infection of hate that has spread across Wyndebrel, even when their numbers seem so small compared to the might of their enemies, they must hold true to their mission: to create a better and safer realm for everyone.

With the aid of Eyrewood, Fairkeep, and the dragons, they are as ready as they'll ever be to ride on Helston and Dumoor, to confront the newly crowned King Peran and the Witch Queen, and finally define what peace truly means. And there is a single truth Callie and friends must cling to: The battle is still worth fighting even when victory seems impossible.
