The Sinner's Vow

Two rival monsters. One decimated city. A vow forged in blood.

Nivrea is the Eraser. A lethal, untouchable ghost employed by the underworld to make their worst problems disappear. She survives by adhering to one absolute rule: never let anyone close enough to see the cracks in her armor. She is a weapon, and weapons do not have a heart to break.

Kavrak Morvath is the Architect. The apex predator of Oestrinova's most ruthless syndicate. For three years, he has watched Nivrea from the shadows, obsessively building an empire-and a heavily fortified, velvet-lined cage-worthy of the only woman who equals his darkness.

When a sociopathic mutual enemy guts their city and captures Nivrea's young apprentice, the two deadliest rivals in Oestrinova are forced into a bitter, temporary alliance. To save the only family she has left, Nivrea must walk into Kavrak's fortress.

He offers her his army, his resources, and his absolute, terrifying devotion. But the Architect doesn't just want her cooperation to win a war. He wants her soul.

Trapped in a twisted symbiosis of violence and undeniable magnetism, Nivrea must decide if she is willing to surrender her autonomy to the monster who worships her, or if she will burn his empire to the ground to keep her freedom. But as the city burns around them, she realizes a terrifying truth: Kavrak's darkness doesn't threaten hers. It cradles it.

The Sinner's Vow is a dark, intense, and psychologically heavy syndicate romance featuring a fiercely independent assassin and a violently possessive kingpin who will tear the world apart to claim her. Expect high-stakes action, moral ambiguity, and a breathtaking "touch her and you die" romance. Intended for mature audiences.
