In the border village of Thornhaven, Elara Blackthorn hides a magic that shouldn't exist in a human body. But when the legendary Blood Treaty requires her to be bonded to the Prince of Thorns, her secret becomes a destiny she cannot escape.
Tethered to the guarded Prince Cassian, Elara must navigate the treacherous Court of Living Wood to uncover the truth of her heritage. With the Thornwood dying and enemies closing in, Elara and Cassian must choose: uphold an ancient duty, or surrender to a love that could rewrite the laws of magic forever.
