The Poison Daughter

By Sheila Masterson

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.

Possibly my favorite book of the year! The plot was so interesting, I loved the writing, and the characters were incredible. The twist with Aidia being dead literally made my jaw drop. I really enjoyed the push and pull between Harlow and Henry. Harlow is such a badass and a true feminist icon. Although she has a lot of trauma to work through, I'm so happy she has Henry with her. The way their stories relate are so perfect. The way he is feral for her but ALWAYS respects her boundaries and listens for consent!!! Also, Kellan being Rochelli! Stop it. It may be because I stayed up until 1am to finish this and my brain was going slow but I really was expecting it to be Henry or some side character. Anyway, 10/10 I'm sad I can't read more about their life together.
