HELENA is the ice queen of Wall Street. When cancer stole her fertility, she didn’t grieve—she treated her survival as a corporate restructuring. She bought the perfect biological vessel. A million-dollar shadow trust, a flawless isolation period, and an iron-clad NDA. It was supposed to be a clean transaction. Until the child is born, and the surrogate refuses to leave. JULIAN is an aesthetic genius trapped in a concrete cage. Years of walking on eggshells around his powerful wife have left him emotionally castrated. Then Luna moves into the guest suite as the live-in nanny, smelling of sweet milk and submissive warmth, filling every sterile corner Helena left empty. Week one, Luna begins wearing Helena’s discontinued vintage Chanel. Week two, the baby violently screams every time Helena tries to hold him. Week three, Helena wakes up at 2:00 AM to find Luna standing in front of the master mirror, wearing her silk slip, practicing her corporate speeches with flawless precision. In this minimalist mansion of glass and shadows, a parasitic takeover has begun. But Luna made one fatal mistake: she forgot that before Helena was a mother, she was Wall Street’s most cold-blooded executioner.
