Mara Cole doesn't remember how she got to Noirheim.One moment she was working her night shift at the archive library. The next, she opened her eyes to a vaulted ceiling carved with symbols she couldn't read — in a mansion that doesn't exist on any map, in a city swallowed by permanent fog.The man standing at the foot of her bed is Caelum Voss. CEO. Crime lord. The most feared man in Noirheim. Cold, broken, and in complete control of everything except the girl who arrived at his door in a way that should have been impossible.She was called to Noirheim. By something ancient living in the walls. By a curse written in a dead language on the foundation stones of a city built on bones.She is the key to breaking it. He is the only one who can protect her long enough to try.And somewhere between his obsession and her courage something neither of them planned begins to grow.In Noirheim, the darkness doesn't just surround you. It watches. It waits. And sometimes it falls in love.
