The kingdom of Cansere is on the brink of war. Young men are conscripted from their homes, and a royal decree from the queen has made healing the only legal form of craftlock. Nym, a healer and beekeeper, is the sole provider for her family of seven now that her younger brother has been sent to the war front. But when a letter comes from the queen, summoning Nym to the palace to heal Prince Renn, the kingdom’s ailing shut-in, Nym finds herself making the tumultuous journey from her family’s apiary to the capital city. Nym is determined to fail the queen’s mission and return to her younger siblings as soon as she can.

But escaping the castle’s hold isn’t as easy as failing a simple test. Prince Renn is cold and distant, and his illness is like nothing Nym has ever seen before, nothing she could ever imagine treating. In a moment of connection with Prince Renn, Nym manages to remedy the faintest symptom of his ailment–only to discover that no healer before has made such progress. Forced to become the prince’s official healer and a ward of the castle, and with her only hope of returning to her family hinging on the prince’s recovery, Nym must navigate the castle’s cruel and twisted court and uncover the haunting truth behind Prince Renn’s illness–even as she finds herself irrevocably drawn to him.
