The Briarwild

Every hundred years, the forest opens.
The villagers of Fernhollow whisper of the Thorn King-a vengeful spirit bound to the heart of the Briarwild, who demands a bride to keep his wrath from spilling beyond the tree line. When Elira's younger sister, Maeve, is chosen, Elira steps forward instead.
Not only out of love, but from a long-held curiosity that's pulled her toward the forest all her life.
But the Thorn King is not the monster she expected.
Within the overgrown ruins of his crumbling court, Elira finds a being more sorrowful than savage, and a forest that feels as wounded as it is wild. As the garden blooms beneath her hands and forgotten magic stirs in the soil, Elira uncovers fragments of a curse twisted by fear, heartbreak, and centuries of silence.
To break it, she must do what no one has dared-love the forest, not for what it offers, but for what it is.
