Poisonous Vow

“Till death do us part” wasn’t a promise. It was a thirty-five-day death sentence.

Zinovia Veltri is an architect of death.

Raised in the toxic glasshouses of her family’s criminal empire, she has spent her life synthesizing bespoke poisons and navigating the brutal politics of the Crovenco syndicates.

When she is offered up as a sacrificial bride to cement a precarious truce with her family’s greatest rivals, she expects a cold, loveless prison.

She doesn't expect the wedding toast to be laced with the Requiem Toxin.

Nicander Vargos—the Butcher of the Docks—hates the Veltri bloodline with a visceral, violent intensity.

As the most feared enforcer in the city, he planned to use the arranged marriage to dismantle his enemies from the inside.

But as the altar becomes a trap and a necrotic, incurable venom enters both their veins, his vow to destroy his new bride is overridden by a singular, terrifying necessity: survival.

Betrayed by their own blood, stripped of their empires, and given exactly thirty-five days before their cellular structures liquefy, the ultimate enemies are forced into a lethal alliance.

The only cure has been stolen, hidden in a heavily fortified island bunker by a traitor looking to sanitize the city’s underworld.

To get it back, the toxicologist and the butcher will have to wage a two-person, scorched-earth war against an army of mercenaries.

But the ticking biological clock isn't the most dangerous thing coursing through their veins.

Forced into agonizing proximity, the icy, generational hatred between them violently ignites into a blistering, desperate obsession.

As the poison breaks down their bodies, Nicander realizes he will burn the entire city to the bedrock just to keep his wife breathing.

And Zinovia discovers that the only thing more terrifying than the grave…

is surviving the poison only to be entirely consumed by her husband.
