When a witch with fire in her veins and an assassin with a hollow heart collide, their love could save the world-or reduce it to ash." Lysara Veyne never asked to inherit a curse that could unleash a primordial demon. But when a shadowy mercenary kidnaps her, demanding she fulfill a deadly covenant, she learns her blood holds a power that could rewrite fate itself. Kieran Sable, a brooding assassin haunted by visions of her death, is the only one who can protect her-even if he's also the reason she'll burn. As they unravel centuries-old secrets tied to a gothic church and a demonic pact, their forbidden attraction ignites a fire neither can control. But with every kiss, the Hollowing grows stronger. To survive, they must choose: betray their hearts or watch the world crumble. In a world where love is the deadliest weapon, can two broken souls rewrite a prophecy written in blood-or will their passion become the spark that ends it all? Perfect for fans of Sarah J. Maas's steamy, action-packed romances and Leigh Bardugo's dark, twisted magic. Tropes you'll love: Forbidden love - Only one bed - Hurt/comfort - "Who did this to you?" - Soulbound mates. A heart-pounding blend of Ninth House mystery and Crescent City heat.
