What a dreadful disaster.
The Poisoner is essentially Haunting Adeline, with the rapist being a vampire and the extremely obnoxious victim being a so-called poisoner who spends the entire active plot failing at being a poisoner. Though, there is no plot, save for the porn, porn, and more porn. Plus the author's rape fantasies.
The story begins with the protagonist, who is just SO not like other girls, attending her friend's party, where the author makes pitiful attempts at making the dialogue sound old-timey. Alina immediately stumbles on the vampire rapist murdering a young woman, and despite the fact that her entire profession is based on killing abusive men to protect women, she does absolutely nothing about this, and leaves the woman to be murdered by the vampire rapist. Totally makes sense for her character, right?
She then immediately starts being stalked by the vampire rapist, who is just a silly goofy guy playing some games! Cue the scenes cut straight from Haunting Adeline with names replaced and vampire fangs added, i.e. the stupid hide and seek bullshit. The vampire rapist gives Alina multiple serious injuries, such as a concussion and a gash in her head requiring stitches, and also torments her by leaving dead animals and body parts in her house. He makes several advances on her, in which she screams no and does not give him consent, but he does it anyway, and she magically ends up liking it because people, for some reason, love to romanticize abuse and rape. Again, Haunting Adeline.
The majority of the book completely lacks a plot, with chapters jumping around between instances of the vampire rapist tormenting Alina. The vampire rapist also, for some reason, has his own perspective in chapters, though this adds absolutely nothing to the story. He's extremely inconsistent, first saying he can't wait to murder her, then wanting to fuck her and murder her, then just wanting to fuck her, then saying he was never intending on murdering her at all and just wanted to have her to himself. Vampire rapist needs to get a hobby.
The only plotline that exists in this story is that Alina has accidentally poisoned some of the vampires, and the big bad mafia leader vampire is mad at her and wants to have her killed for that. However, her poisons never did anything to vampire rapist, so I'm not sure why big bad mafia man cares so much that someone is failing miserably at killing his little vampire babies. The poisons do not effect at them at all. But whatever. It's fine. The only plotline doesn't make sense and also doesn't play into the story at all until the very end.
Cue the part of the story where Alina is kidnapped by vampire rapist #2, who pretended to be her friend all along, and when he inevitably rapes her, she doesn't like it, even though vampire rapist #1 effectively did the exact same things to her but for some reason, she loved it. Neither had her consent, and yet... Another stupid Haunting Adeline-ism.
Vampire rapist #1, who is just so in love with Alina, does nothing about rapist #2 raping her, and instead goes to her bed in the middle of the night with him to feed on her and grope her without her consent. Huh. Almost like that's a common theme. Vampire rapist #1 literally murdered some random guy for being mean to her, but when another vampire rapes her, he doesn't care. Cute. Such a true romance, right? What a green flag of a man!
The book wraps up with a very anticlimactic ending, which doesn't surprise me, since there was no substance to the rest of the book anyway, I don't know why I thought the ending would be better. And for some reason, this isn't a standalone, because the author just NEEDS to write more vampire rape fantasy porn.
Don't take this the wrong way- I love a smutty book, and I'm into dark fantasy. This is not dark fantasy. This is rape and abuse, straight through, with the author pretending all of it (save for the second rapist part) is kinky and consensual. It is not consensual when Alina screams no at vampire rapist #1 for half of the book. This is a distasteful addition to the books that I've read, which is extremely sad because I was excited to read this book when I first read the synopsis.
So to sum it up; don't read this, except as a little piece of entertainment when you're bored in a reading slump. Or unless you also like romanticizing literal rape and assault.
As Tyra Banks said, "It's so bad, I want to give it a zero. But that's not possible, so I give you... a one."
