Friend, Lover, Killer

by S.E. Green

She writes about killers. She never meant to become one. Lola Dahl is a bestselling thriller author whose career is quietly unraveling. Her last book flopped. Her publisher is losing patience. And the words—the good ones—have stopped coming. Then Lola kills someone. It isn't planned. It isn't justified. But something terrifying happens in the her creativity roars back to life. The story pours out of her. The pages fly. For the first time in years, she feels unstoppable.

As Lola channels her darkest impulses into a new manuscript about a vigilante named Nyx—a woman hunting those who profit from human suffering—the lines between fiction and reality begin to blur. Each death sharpens her focus. Each secret pushes her closer to discovery. And somewhere out there, someone may be watching her far more closely than she realizes.

"Friend, Lover, Killer" is a chilling psychological thriller about obsession, moral rot, and the dangerous thrill of getting away with murder. Told through an intimate first-person voice, it dares you to root for a protagonist you should never trust—and won't be able to forget. Some stories are worth killing for.

Lola writes dark thrillers. She’s successful, but her last book was a flop. Her publisher wants a new book right away. Lola has to get out of her slump, but has no ideas… until she begins to research old enemies . Is there a new story there?

A crazy tale of a writer who will go to any lengths for her next novel. A great read, for sure.

This was SUCH a dark and twisted read! Honestly, I was hooked by the concept alone. You have a thriller writer who accidentally kills someone, and instead of falling apart, it basically unlocks her creativity again. Like WHAT?? From there she turns into this vigilante killer, only going after people who got away with horrible crimes, and every kill fuels her writing. It is messed up but also weirdly fascinating to watch unfold. PEAK ADDICTIVE ENERGY. 📖🔥

I really liked the structure of this book too. You get her real life chapters and then the chapters from the book she is writing, and the way those start blending together is SOOOOOOOOOOOOO GOOD. It makes everything feel more intense and a little unhinged in the best way. It is a total mind trip! And then there is the whole stalker element? The drawings showing scenes from her past books and the messages after each murder had me like okay wait, who is watching her?? That added a whole extra layer of tension that was FREAKING INTENSE. 🎨👣

Lola as a character is a LOT. She has a rough past, and while you understand parts of her, you also know she is completely spiraling. It is one of those books where you are kind of rooting for her but also like “this is VERY wrong” at the same time. The audacity of her transition into a vigilante is wild! It is clever, engaging, and pulls you right into her messed-up head. IT’S THE REAL DEAL. 🧠💀

If you like dark thrillers, vigilante justice vibes, and morally messed up main characters, this is definitely worth picking up. It is creepy, addictive, and keeps you questioning everything until the very end. I could not put it down! It is a total win for anyone who loves a gritty, psychological story with no filler!!!!!!!! 🌟🔪

TOTAL 8/10. A TWISTED MUST-READ! A1. 🏆🖤

A dark thriller writer accidentally kills a man, then she goes on a spree as a vigilante killer, murdering only those who have committed major crimes that slipped through the cracks of the justice system. These murders ignite her inspiration for her latest novel that everyone from her agent to the publisher is saying it is her best work yet. Will she be caught for these crimes?

In between her chapters are the chapters she is writing for her latest book. She is also being sent drawings of images depicting scenes from her previous books and then sent messages after each of her real-life killings. Is she being stalked?

I would recommend this book if you like vigilante killings and a woman with a horrible childhood that has made a life for herself

Friend. Lover. Killer is a thriller by S E Green. I feel that this book is a serial killer/author, thriller, and a horror story rolled into a very well written book. When Lola has writers block, she commits a murder and the words flow. In my opinion, the author really describes the victim well and gets inside Lola's mind while she is murdering. I feel the book is dark and if horror/thrillers are books you enjoy… I believe that this story is one you will enjoy. I received an arc for free and am leaving my review voluntarily.

OUTSTANDING!

Holy shizz, Ms. Green! I haven’t read all of your work, but now plan to dig into the back catalogue. This book? It is EVERYTHING. (Especially topical these days. ) Funny, as I was finishing this today, my ex texted me and asked if he had left his baseball bat here when he moved out two weeks ago. It is now sitting next to me on the couch. I told him to come and get it. 😉 Thanks for a fantastic read! All the stars, highly recommended!

Cool idea for a plot involving the author and the unique ways she gets her ideas for the story. The events are dark but tastefully written and the twist kept me guessing to the shocking end. I enjoyed reading this and will recommend it to fellow readers.

S.E. Green never disappoints. Her thrillers are AWESOME - lots of surprises and so entertaining. They all will have you at the edge of your seat as you read. I'm making my way through all of her books. I highly recommend you do too!

Feels like a 4⭐… but just barely 🤔

[Sabrina · Rating 2 out of 5]

2.5 ⭐️ It just missed the mark for me. Not enough time was spent on the characters to help develop the story that was being told. It definitely had potential.
