Under His Command: A Dark Mafia Noir

by Quinn Calder

“Viruses are not debated. They are quarantined.”

Sofia Mortello was never meant to exist inside the system that created her.

Raised within the quiet power of the Mortello family, she understands the rules that govern men like her father. Power is not declared. It is maintained. Stability is everything.

But stability is fragile.

Within the iron hierarchies of the Bratva, Sofia uncovers a hidden oversight mechanism examining the foundations of her husband’s authority.

And the moment it notices her—

everything changes.

She becomes something far more dangerous than a political liability.

She becomes an anomaly.

What follows is not investigation or negotiation. It is containment. Files open. Classifications shift. Decisions move through corridors where nothing is recorded twice.

And Sofia is no longer outside it.

As pressure tightens, she uncovers something far worse than corruption beneath the architecture of power.

A system built to observe, isolate, and eliminate anything that threatens its stability.

A system that studies deviation the way a scientist studies disease.

Because in systems built on absolute control, anomalies are not reasoned with.

They are corrected.

But systems adapt.

And Sofia was never meant to be understood—

only contained.

This was a very WOW book, I could not put it down. This book had me in such a chokehold, the premise was awesome and the psychological aspect was beautifully disturbing. I had a love/hate with the MMC but he still had me drooling😁 This was my first time reading this author and now I can't wait to go back and read book1.

I’m not sure what I thought of this book if I’m honest. The story was good but it used so many of the same words throughout that for me personally it became annoying. Having said that everyone enjoys different things so I would recommend it.

Definitely a different kind of book. I’m still not sure how I feel about it. It kept my interest but I’m still sorting out the system. If you’re looking for steamy, it’s not that kind of book. More psychological drama than anything.
