He was supposed to break her. Not crave her.

Echo Kane doesn’t make mistakes. As the merciless head of Catalyst, his job is dismantle the Romanov legacy, one corpse at a time. But when Katya Romanov ends up in his hands, defiant, dangerous, and sin wrapped in skin, his carefully built world begins to crack.

She’s the daughter of his sworn enemy. She’s leverage. A means to an end.

So why does he want to taste her screams? Why does he dream of her begging, not for freedom, but for more?

Katya is no innocent. Raised in the shadows of blood and betrayal, she’s been trained to survive men like Echo. But no one warned her what it would feel like to be claimed by him. To ache for the same hands that bruise. To crave the same mouth that lies.

As obsession smolders into something darker, neither of them can tell where hate ends and hunger begins. Loyalties fracture. Bodies fall. And in a world where every character bleeds morally grey, love isn’t salvation, it’s a war.

In the third installment of Katerina St Clair’s Shadows of Darkness universe, Devil’s Night is a dark romance soaked in desire, deception, and the kind of heat that scorches more than skin.
