A Breton princess at the peak of the French Renaissance, Lilac lives prisoner in her parents' castle after a wicked secret is revealed on the eve of her 10th birthday soirée. Years later, her coronation ceremony looms, and between the riotous townsfolk and scheming nobleman bent on snatching the throne, Lilac prepares for the worst...until a mysterious letter arrives from The Witch of Lupine Grotto, detailing a curious offer to cure her darkness forever.

Lilac begrudgingly trades her coronet for a cloak and ventures into the forest Brocéliande in pursuit of the impious enchantress at the edge of town. With only the protection of an inherited dagger - and unsolicited help of the gregarious stranger who inserts himself on her quest - she must traverse Brocèliande and return in time to claim her rightful position as sovereign monarch.

This is the story of a cursed princess, a crestfallen killer, the town that wants them to burn, and the witch that can save them both.
