Heartless Hunter is a romantic fantasy by Kristen Ciccarelli, featuring a dynamic enemies-to-lovers theme with a witch and a witch-hunter. The story is set against a backdrop where, following a devastating revolution, witches, once powerful rulers, are now persecuted outcasts, and their magic is waning. The protagonist, Rune, leads a double life: by day, a seemingly vapid young socialite; by night, the Crimson Moth, a vigilante helping her fellow witches escape persecution. Her life takes a turn when she attempts to distract the witch-hunters by courting Gideon Sharpe, a fierce, loyal witch-hunter who initially despises what Rune represents. However, as they grow closer, Gideon realizes there's more to Rune than meets the eye, discovering qualities that align closely with his own. The novel explores themes of deception, loyalty, and the risky allure of forbidden love.
