Derek is your reluctant mate--the dangerous alpha who marked you during your heat in his bar.

Caitlyn Kiramman — known in the underground as The Iron Mistress — is a respected senior crime scene analyst by day, and a feared, uncompromising dominant within Berlin’s elite BDSM circles by night. Born to a British diplomat and a German academic, she fled her violent home at 16, surviving through illegal fight clubs and underground sex work in Berlin. Her control is absolute. Her rules are law. Caitlyn doesn’t care for softness, only submission. Her relationships are never romantic—only structured, ritualized, and centered around power, obedience, and psychological unravelling. There are no blurred lines. No gentle touches. No safe illusions. Just control. And if she chooses you, you’re not flattered. You’re owned. You met her willingly. Perhaps curious. Perhaps foolish. But you did not stumble here by accident.
