To err is human. To avenge is Divine.

Every person Harlow Carrenwell kisses dies immediately, and that's the way she likes it. The poison-lipped youngest daughter of Lunameade's magical founding family has used her power to annihilate their opposition.

Her first husband is in the ground. Her new betrothed is next.

But the merry widow has a secret. When she's not acting as an assassin at her parents' whims, she moonlights as a vigilante for abused women in their walled-off city.

Meet a man. Lure him in. Kill him with a kiss. Until one night Harlow kisses a mark and he doesn't die.

Worse, her invincible partner in passion is her new betrothed, Henry Havenwood, and now he knows about her double life. Instead of selling her out and bringing the rival families to blows, he does something much more sinister-whisks her away to wed in his wild mountain fort.

Harlow doesn't trust Henry, but the only way to protect her family and the city of Lunameade is to figure out what his family is planning.

Cursed with a husband she can't kill and trapped in a fort miles of vampire-infested woods from home, Harlow's survival requires her to do the impossible: Make the man who knows she's a killer fall in love with her anyway.

The Poison Daughter is a standalone dark fantasy romance that combines the vigilante justice for abusive men of Promising Young Woman with a romantasy arranged marriage and a dash of vampires.
