Blurb:

To destroy the vampires who killed her family… she must become one of them.

Nadi is trapped in a deadly alliance with Raziel Nostrom. After a honeymoon soaked in blood and desire, they make a pact—to take down his criminal family together.

Now Nadi is at the heart of the Nostrom empire, pretending to be a vampire. If her act slips even for a moment, they will tear her apart.

Raziel holds Nadi’s life in his hands. And her heart… His wicked smile sets her body aflame, drawing her closer and closer. Still, he is a born killer—alluring and utterly ruthless. He could turn on her in an instant.

But Raziel is not the only one in his family with a taste for betrayal…

When his brother and sister approach her with proposals of their own, Nadi faces a desperate choice. Will she stand by Raziel, as the world turns against him? Or seize the perfect chance to destroy his family forever?

My Review:

Chaos, cruelty, desire, this book thrives in the gray space where love and destruction blur together.

The Serpent’s Sin wastes no time throwing you back into the wreckage left behind by book one. The uneasy partnership between Nadi and Raziel shifts into something far more dangerous: an alliance fueled by obsession, violence, and undeniable attraction. Every interaction crackles with tension, and nothing about their connection feels safe, or sane.

This installment leans hard into the darkness. The world is brutal, the characters are morally corrupt, and the stakes are higher than ever. But what truly elevates this book is how much deeper it goes emotionally. Raziel, who was already compelling, becomes painfully human as his past is peeled apart piece by piece. His family history is twisted, toxic, and formative in ways that explain so much of the monster he’s become. Watching him reveal those scars to Nadi adds unexpected vulnerability to a character who thrives on control.

Nadi, meanwhile, is standing at a crossroads. Her lifelong hunger for vengeance collides with feelings she never planned for, forcing her to confront who she is beyond revenge and whether her loyalty is as unshakable as she once believed. The internal conflict she faces makes every choice feel heavy, and dangerous.

Just when you think you’ve caught your breath, the story rips the ground out from under you. The pacing is relentless, the twists hit hard, and the ending arrives far too quickly, leaving that familiar mix of shock, frustration, and desperate need for more. Raziel’s family only becomes more infuriating, the power dynamics grow more volatile, and the line between love and ruin completely disappears.

This is how you do a sequel, raising the emotional stakes, deepening the characters, and making the wait for the next book feel downright cruel. I am beyond ready to see just how far Nadi and Raziel are willing to go to finish what they started.
