Roman Kalashov is a successful businessman with interests in import/export, real estate, and private equity. He's built an empire from the ground up, commands respect in every room he enters, and maintains the kind of lifestyle most people only dream about. He's also a single father to his six-year-old son, Nikolai, who means more to him than anything else in the world. In a life built on calculated risks and necessary violence, Nikolai is the only purely good thing Roman has ever created—and he would burn the world down to keep him safe.

After his well-meaning sister stages yet another intervention in his kitchen, Roman has reluctantly agreed to hire a live-in nanny. Someone to provide structure, routine, and apparently vegetables that aren't deep-fried. Someone trustworthy enough to care for his son when business takes him away from home. Someone who knows when to look the other way and understands that curiosity, while admirable in most professions, can be a dangerous quality in this one.

Nikolai's mother, Karina, is a calculating woman who saw Roman as a meal ticket and their son as leverage. She got a generous settlement and minimal custody. Roman got his son and a permanent reminder that trusting the wrong person can cost you everything. He won't make that mistake again.

The estate is beautiful, the pay is excellent, and the rules are simple: take care of Nikolai, respect boundaries, and don't go where you're not invited. Especially the basement. It's just storage, after all. Nothing worth seeing. Nothing worth mentioning. And if you're smart, you'll keep it that way.
