"Have you ever wondered how long it would take for a lethal dose of arsenic to kill you? Thirty\-five hours, twenty\-nine minutes, and fifteen seconds. I should know. I counted myself." Amidst the gaslit alleys and cobblestone streets of Victorian London, two killers find themselves entangled in a waltz they cannot escape. Alina Lis, a botanist and hobbyist poisoner, has a pastime of killing unsavory men in her twisted sense of poetic justice. When she targets the conceited playboy, Silas Forbes, only to find him in her apothecary the following week, she discovers human men are the least of her problems. The pair’s unlikely association sparks gossip among affluent society. As their mysterious bond deepens, a chilling truth emerges—concealed identities, lurking foes, and questions as plentiful as the hydra’s head brew within this haunting Gothic tale of violent passion. Will Silas and Alina find themselves in each other's arms, or will the shadows of their past keep them apart?

In the shadows of 1890s Buffalo, a poisoner's bite leaves more than just scars—even for the undead. Two years after fleeing London, Alina Lis has built something she never thought a home. Leading a commune of women like herself, she's found a new, greater purpose; experimenting on the Vipera. But peace, she learns, is as fragile as a spider's web in winter. Silas Forbes, the Vipera she escaped, hasn’t forgotten. But his thirst for Alina threatens everything he's created in her absence. And he's brought another along for the Luka Novikov, the man who once betrayed her, now bound to them both by wounds that won't heal and debts that can't be paid. As human and Vipera worlds violently collide, old poisons surface and new alliances form. In a society where survival means choosing sides, Alina must protect the family she's built, Silas must decide what price he'll pay for his obsession, and Luka—marked forever by the poisoner's kiss—must survive the clash of an immortal’s longing and a woman’s fury. Some venoms have no antidote. Some hungers can never be satisfied. THE ARACHNID is the second installment of the darkly seductive POISONER SERIES, where humans and Vipera twist together like lovers in the dark.
