Runevein makes a living breaking curses—cleanly, quietly, and without getting attached. So when a powerful noble household hires her to purge a “social sickness” spreading through their castle, she expects hidden sigils, old blood, and the usual lies wrapped in velvet. She doesn’t expect the castle to breathe her name. She doesn’t expect four dangerous lords to watch her like hunger given Vesperthorn, a vampire with patience sharp enough to cut; Solvane, a sun-mage who cages darkness with rules and light; Garrick Ashmantle, a knight bound by vows that look too much like chains; and Keystone, the sentient spirit of the castle itself—possessive, omnipresent, and whispering promises through stone. The curse is supposed to be in the walls. But the moment Runevein steps inside, desire turns volatile—confessions slip, restraint fractures, and every glance feels like a spark near spilled oil. The more she fights for control, the more the castle tightens around her… and the more the lords decide they don’t want the curse cured. They want her. And Runevein is about to learn the most dangerous kind of magic isn’t the spell you break — it’s the one that binds by choice.
