After a whirlwind romance, Savannah says "yes" to marriage, and the two settle into Bennett's secluded upstate home.

But just as Savannah thinks she has it made, cracks appear in her perfect new life. Bennett's behavior becomes dark and he criticizes Savannah’s writing, dictates her permitted activities, and spends most of his time locked in his office, forbidding her from entering. And everywhere, Savannah cannot escape the shadow of Bennett's first wife, the free-spirited and passionate artist Poppy, who died in a tragic accident, but who seems still to be Savannah’s rival for Bennett's affection.

I gobbled this one up in a day.

Novelist Bennett Bryson's debut made him rich and famous.

Everything following it has landed a step lower than the book before.

His agent has been clear: to compete in the current publishing market, he must turn out a book a year...preferably a bestseller.

This is a man who's built a life — a stately home on 14 acres in Bedford, New York; an Aston Martin and Range Rover in the garage; Cartier watches on his wrist — on a single blockbuster.

Sadly, he's spent the past 15 years terrified that it's the only one in him.

Enter Savannah Brooks, an ambitious assistant at a New York literary agency. An aspiring author herself, Savannah's been quietly studying the recently widowed Bennett Bryson, her boss’s most famous client.

Savannah positions herself at a writers’ conference to meet him.

Following a whirlwind romance, the two marry, Savannah leaves her job in Manhattan, and moves into Bennett's 5,000-square-foot colonial home in Bedford.

The dream begins to crack almost immediately...and that's all I'm gonna say about that.

Fans of Liv Constantine’s previous work, especially The Last Mrs. Parrish, will enjoy this fast-paced domestic suspense with continuous twists.

The reigning sisters of thriller royalty have done it again—and yes, I inhaled this in one sitting like it was oxygen. This is a full-on nail-biting, edge-of-your-seat, eyes-wide-open domestic thriller that blends mystery with obsession, betrayal, jealousy, control, gaslighting, and some truly delicious power plays. The pacing? Relentless. The multi-POV structure? Basically a trail of perfectly scattered breadcrumbs that had me flipping pages like my life depended on it. Every chapter tightens the knot. Every twist lands with precision. And just when you think you’ve cracked it—BAM—the rug is violently pulled out from under you. That final stretch? Absolutely unhinged in the best way.

At the center of the chaos is Savannah, who goes from being a publicist’s assistant to the brand-new wife of reclusive horror megastar Bennett Bryson. Yes, that Bennett—the brooding, work-obsessed author living in his isolated estate with his eerily ever-present caretaker, Felicia (who also happens to have been his babysitter… because of course she was). Their whirlwind marriage comes just months after Bennett’s first wife, Poppy, tragically drowned in a boating accident. Red flag? More like a parade.

Savannah has long idolized Bennett and dreams of becoming a successful writer herself, but marriage quickly shatters the fantasy. Bennett is controlling, secretive, and fiercely territorial about his work—his office is off-limits, her social life is quietly suffocated, and her writing is picked apart with surgical cruelty. Then come the anonymous messages… warning her that Bennett isn’t who he claims to be—and that Poppy’s death might not have been an accident after all. And maybe Poppy isn’t the only one whose story ended badly around him…

So the question becomes: is Savannah living a dream—or walking straight into a nightmare?

I won’t spoil anything (you’re welcome), but let’s be honest—this isn’t a flawless five-star read, and that’s okay. Savannah, at times, made me want to gently (or not so gently) shake her—she’s a bit too naïve, overly eager to be “the wife,” and could definitely use a confidence boost and a backbone upgrade. Meanwhile, Bennett is basically radiating “something is very wrong here” energy from page one. And Poppy? Honestly, she might have been my favorite—bold, artistic, self-assured, and unapologetically alive in a way that lingers even in absence.

Yes, there are a few familiar thriller beats and some slightly over-the-top moments, but none of that stopped me from devouring this like premium popcorn. Because the ending? Completely worth it. I had my suspicions circling a couple of characters, but certain reveals still managed to smack me across the face—in the most satisfying way.

So yes, I’m happily rounding this up to a solid 4 stars. Because when these brilliant sisters write, I simply refuse to rate them lower—they’re just too good at what they do.

Many thanks to NetGalley and Ballantine/Bantam for sharing this addictive, fast-paced domestic thriller with me in exchange for my honest thoughts.

Liv Constantine, will you promise me another book after this one? 😉 I sure had fun with this quick, fast paced read!

This story starts out with Savannah, who works as an editor’s assistant, finally getting the chance to meet the author/man of her dreams. Bennett Bryson, the famous horror author, is speaking at a convention that she and her boss will be at. As luck would have it, the attraction is instant. Savannah and Bennett have a whirlwind romance, and then an even faster marriage. How convenient, as Savannah is aspiring to become a writer herself ✍️

Upon their marriage, Savannah moves into Bennett’s beautiful, secluded mansion. Once there, Savannah learns how lonely it is, as Bennett locks himself in his office all day to write, and no one is allowed in there. That is the only space in the house that is off limits. What is be hiding? And why have all Bennett’s previous girlfriends abandoned him- especially when he is so handsome and charming? (Oh, and let’s not forget wealthy).
And why does Savannah feel that she is not good enough anymore? Why does she feel that she is in competition with his dead wife, Poppy?

If you want all the answers to these questions, then I highly recommend you read this book! There were a few twists thrown in this book that kept me turning the pages faster and faster! I always enjoys books by Liv Constantine, and this book did not disappoint!

Many thanks to NetGalley, Ballantine/Bantam Books, and the author for an advanced DRC of this book, in which I had the pleasure of reading for an honest review.

Thank you to NetGalley and Ballantine/Bantam for the ARC of PROMISE ME NEVER by Liv Constantine. Publication date was August 18, 2026.

Short chapters, cliffhanger endings, unreliable narrators, and plenty of secrets make PROMISE ME NEVER a compulsively readable, character-driven thriller.

Constantine uses three narrators to tell the story of Bennett, a wealthy horror novelist whose romantic history is marked by an alarming amount of tragedy. Bennett achieved tremendous success with one breakout novel and its subsequent film adaptation, but now he’s under pressure to prove he isn’t a one-hit wonder. With a publishing deadline looming, he has only a few months to deliver his long-overdue next book.

Then there’s Bennett’s personal life. His wife has recently died in a tragic boating accident when he meets Savannah, who works for his editor. Their attraction is immediate, and they quickly fall in love. But Bennett’s past raises some unsettling questions, and Savannah may have reasons of her own for entering his life.

Constantine effectively toggles between the present and “before,” gradually allowing Bennett’s late wife to reveal what their marriage was really like in the months leading up to her death. Meanwhile, Savannah and Bennett narrate the present, and it soon becomes clear that neither is telling the reader everything.

This is where Constantine excels: nearly everyone gives off unreliable-narrator vibes. Who is lying? Who is manipulating whom? And exactly how much bad luck can one man have with the women he loves before it stops looking like bad luck?

As Savannah becomes increasingly vulnerable, the suspense builds around the possibility that she could become yet another casualty in Bennett’s disturbing romantic history. The short chapters and frequent cliffhangers keep the pages turning as the reader tries to piece together what happened to the women who came before her.

As an avid thriller reader, I especially appreciate a final twist I genuinely don’t see coming. Constantine got me. Just when I thought I had everything figured out, she pulled the rug out from under me.

Fans of Liv Constantine’s THE LAST MRS. PARRISH should find plenty to enjoy here: wealth, secrets, manipulation, questionable motives, and characters who are never quite what they seem.

A fast, twisty, highly entertaining thriller.

How much is a promise from a best-selling horror author worth?

Will his love last forever?

Savannah wants to believe it. A life of luxury and everyday access to a writing coach you really love? It's everything she ever wanted.

Not so fast!

This new title from Liv Constantine may keep you up past your bedtime.

Here are some things I liked:

📚Bennett Bryson has a string of bestsellers including his first smash hit PROMISE ME NEVER. As we get to know him better we wonder about his locked office, the mysterious death of his first wife Poppy, and other past relationships.

🤩Savannah Brooks is star-struck when she first meets Bennett Bryson. Can he really be interested in her? There are hints that she also has secrets in her metaphorical closet.

🥨There are some entertaining twists and turns and the short chapters kept those pages turning. The big reveal was something I did guess, but only at the last minute. Then there's more! Too much? Possibly.

🤖Liv Constantine includes an AI reference and it fits in perfectly. How many people are making money off of other people's work by using AI immorally?

The bedroom activities were mentioned too many times for me. Not in great detail, just brought up so much it became repetitive. One star deducted for that.

Secrets! So many secrets.

Savannah is an aspiring writer working as an assistant at a top publishing company. The company just happens to represent her most favorite horror author, Bennett. After the two meet, they are inseparable and after a whirlwind romance they tie the knot. Ditching her current apartment in the city once they’re married, she moves in to his sprawling estate and realizes Bennett may have a few skeletons in his closet.

I’m kind of torn on this one. On one hand, the chapters were short and kept me flipping those pages and engaged. However, on the other hand, I had a hard time connecting with any of the characters. They just didn’t have enough backstory or depth for me to care one way or another about them. BUT if I just take them at surface level and roll with the story, they worked well as a pool side, psychological thriller. And while one part of the story was predictable another part was not which is definitely a positive.

All in all, it was a propulsive read and I was surprised with one or two plot threads. I would consider this one a good pick to take to the beach or read poolside.

Solid 3.5 stars. Rounded up.

Thanks to NetGalley and a publisher, for my advanced copy in exchange for an honest review.

"Play fast, but don't play in a hurry." (Shaq)

And be careful what you wish for by all means.

Savannah knows that her romantic moments have been few and far between. She's ready to settle down with just the right man. But who exactly is that right man? Well, fate brings her face-to-face with the renowned author, Bennett Bryson. Bennett just so happens to be the headliner at a book fair where Savannah is a literary assistant for his publishing company.

Savannah pulls out all the bells and whistles and is eventually invited out to dinner by Bennett. Clock the hours to a month later and Savannah and Bennett are to be married. She knows very little about him outside of the fact that his first wife, Poppy, died in a boat accident. Her body was never found.

Wedded bliss takes them to Bennett's huge property in Massachusetts. Savannah is a fledgling writer herself and asks Bennett for assistance. He's critical of her work and keeps telling her that her ideas have been overdone by others. Savannah becomes frustrated. She also feels isolated as well. Bennett's desire is for her to continue writing in the plush office that he has arranged for her.

Now if Bluebeard's wife had Pandora's Box sitting upon her lap, you'd get the gist of all this. Our Savannah didn't kick the tires before signing on to this wedding and future. Bennett becomes short tempered when Savannah asks about his first wife Poppy and the other two women who were engaged to him. He also keeps his office locked and refuses admittance to Savannah. Some of his mannerisms and behaviors are raising the hairs on Savannah's head. A little too late, girl.

Promise Me Never is one of those books that make your eyes roll out of your head. It tipped the rim for 3 Stars. It brought to mind: "Don't go into the shed with all those chainsaws, girl." Savannah's character was so naive for being a resident of New York City and in her 30's. But we rolled along because Liv Constantine snags us in. The secrets and the twisty twist came in under a low boil. There was a lot of info dump in the conclusion to digest hoping for no bitter taste.

But here's what I would say. It's still a worthy read but don't be as naive as Samantha. Know going in that the connections to the links in this chain don't always mesh well. That's why Constantine had a lot of explainin' to do at the end. I kicked it up to 4 Stars because it did entertain here and there......and I loved the dog, Finn. Check it out.

I received a copy of this book through NetGalley for an honest review. My thanks to Bantam Books and to Liv Constantine for the opportunity.

This was such a fun, twisty read! I was completely hooked by the whole setup. Savannah meets her literary idol, marries him after a whirlwind romance and moves into his secluded home, only to start realising that maybe she doesn't know the man she's married at all. The mysterious death of his first wife, Poppy, and a locked office she's forbidden to enter really ramps up.

I really enjoyed the two timelines and getting Poppy's story alongside Savannah's. The further Savannah digs into Bennett's past, the more suspicious everything becomes, and I was constantly changing my mind about who I could trust.

The first part is definitely a little slower while everything is being set up, but once the secrets start coming out, I flew through this. It's dark, messy and full of the kind of questionable decisions that make you yell at the book while simultaneously turning the pages faster.

I also really liked that Savannah and Poppy aren't quite as straightforward as they initially seem. There are definitely layers to both of them, and the further into the story you get, the more you start questioning what you thought you knew.

The ending did get a little... chaotic and I'm not sure everything landed perfectly for me, but it was a good read with 3.5 stars rounded up.

Thank you Netgalley and Ballantine for the opportunity to read and review this ARC.

COULD NOT put this thriller down.

It contained several requisite big twists as well as several smaller turns which while driving down the road of this novel I did not see coming.

BRAVO to the pair Ms. Constantine and Ms. Constantine...yes did you realize this was a duo of writing sisters? Fabulous work as it's hard to imagine collaborating on a novel. Perhaps one acts as a writer and the other more of an editor? Maybe they trade roles? I plan to look more into their writing process.

The authors hooked me into the storyline quite quickly. Perhaps because of these elements...

~ Most of the novel takes place on the grounds of a remote and stately mansion with rich and classic furnishings...the best that money can buy

~ The mansion is located quite close by car ride to an unprotected wooded area where our protagonist goes daily to walk her great Dane

~ The protagonist's love interest is an extremely wealthy, extremely successful and extremely handsome horror story author

This book felt for a quick minute like it might tip toe over the line from a psychological thriller to a horror story. Even though the tale felt macabre for a bit it did stay in the thriller lane which the synopsis promised.

Are you looking for a thriller to keep you up late into the night? This might be it...it was for me.

3.5 stars, rounded down for initial slowness and the OTT ending. Overall, it was a decent "popcorn" type of thriller, but it got a bit silly with the overly crazy ending, though it was sorta fun. Initially it felt a lot like "Mrs. Parrish" then it turned a bit Freida-esque. Certainly not their best, nor the worst either.

A delightfully dark domestic suspense-meets-popcorn thriller-esque novel, Promise Me Never had me wound around its metaphorical little finger by the time I finished the very first riveting page. I mean, that prologue alone meant I needed to know what was to come in this twisty, fast-paced, one-sitting read. From the Freida McFadden-like plot to the classic Liv Constantine “WTF?!” twists, it was a wild, edge-of-your-seat ride of ratcheting tension and nonstop suspense. Recounted by three true-to-life narrators through short, punchy chapters in both the past and the present, it was an addictive mind game of what everyone was hiding. After all, I knew that this small cast of unreliable characters had some deep, dark secrets in each their closets thanks to a sprinkling of intriguingly vague cliffhangers that kept me guessing.

I do have to say, though, that the eye-popping twists and the action-packed climax went off the rails just a little. Somewhat over-the-top on both counts, they were both deliciously unhinged in the best possible way. Did I have to suspend my disbelief to let myself enjoy the ride? Okay, so maybe I did—but ultimately so what? After all, every time I dive into one of this writing duos’ binge-worthy reads, I know that I’m in for quite a treat—and this time around was certainly no different. Given that I got everything I was expecting plus a satirical view of the literary world and a couple of toxic relationships that made me rethink wanting to date ever again, and this book was nearly as much of a win as my favorite book by them, The Last Mrs. Parrish. So go on. Order this one now. I flew through it, and I bet you will as well. Rating of 4.5 stars.

Read if you’re a fan of:
- Popcorn-ish thrillers
- Marital drama
- A sense of foreboding
- Dark secrets
- Nonstop suspense
- Short chapters
- Jaw-dropping twists
- Multiple POVs
- Unreliable narrators
- Dual timelines
- Literary-world vibes
- Cliffhangers
- Fast-paced plotting

BRIEF BLURB:

In order to get the most out of this book, please oh please go into it at least mostly blind. If, however, you’re one of *those* people, scroll to the end of my review for the full publisher-provided review. Otherwise, all you need to know is…

An aspiring writer named Savannah falls hook, line, and sinker for the renowned horror author Bennett Bryson. Little does she know, but she’s about to get way more than a little career advice. After a whirlwind courtship, she finds herself living in his upstate New York mansion with his ten-carat ring on her finger. Unfortunately, though, she’s not the first Mrs. Bryson—and he’s not the perfect man she’s been dreaming of all this time. Revealing not only a controlling dark side but more than one dead or missing former flame, Savannah begins to look into his past. Will she find out that he’s as dangerous as she fears? And, if so, will she make it out of this marriage alive? After all, he’s not the only one hiding things—and her secrets just might catch up with her first.

Thank you Liv Constantine, Bantam Books, and NetGalley for my complimentary copy. All opinions are my own.

FULL PUBLISHER-PROVIDED SYNOPSIS:

Aspiring writer Savannah’s scheme to meet superstar horror novelist Bennett Bryson turns out better than she ever imagined: not only does her charming and handsome literary idol offer to read her work, he is instantly smitten with her. After a whirlwind romance, Savannah says "yes" to marriage, and the two settle into Bennett's secluded upstate home.

But just as Savannah thinks she has it made, cracks appear in her perfect new life. Bennett's behavior becomes dark and controlling: he criticizes Savannah’s writing, dictates her permitted activities, and spends most of his time locked in his office, forbidding her from entering. And everywhere, Savannah cannot escape the shadow of Bennett's first wife, the free-spirited and passionate artist Poppy, who died in a tragic accident, but who seems still to be Savannah’s rival for Bennett's affection.

Then comes an enigmatic warning: Bennett is not who he seems. The women that came before Savannah have disappeared. And Savannah could be next.

Isolated and unsure whom to trust, Savannah tries to piece together the mystery of the man she married, and the woman he married first. But Savannah has no idea what her husband is really hiding. And someone out there knows Savannah has secrets of her own. As these two writers will learn the hard way—past really is prologue.

Always enjoy the he said/she said drama in a marriage, where the possibility of murder is lurking under the surface. What secret is the wife holding? Why so many former fianceés for the husband? Someone is lying, and as it all goes together, quite the explosion. I picked an entirely different conclusion so it was a happy surprise to find an unexpected one. Will definitely keep reading this author's work.

I listened to Promise Me Never on audiobook and it hooked me quickly. Horror author, Bennett Bryson, is wealthy, attractive, and good in bed. He's also snobby as an author, and oh, by the way, his previous wife died in a boating accident and previous girlfriends have disappeared. Cue the scary music.

Enter Savannah, a budding novelist who works at a literary agency. She has secrets of her own and sets out to meet Bennett. They have a whirlwind romance and a super-fast trip to the alter. Be careful what you wish for.

The final 20% had so many twists that I became concerned about whiplash.

Fabulous fast-paced thriller!

⭐️ 3.5 ⭐️ You can count on Liv Constantine to give you a page turner that will be hard to put down. I mean, I was turning pages faster than I was blinking, I think? Was this well written? No, not really but it was extremely entertaining and I finished this in 4.5 hours while running errands. The overall plot was not that impressive but the eye-popping twists?? UNHINGED.

Ever had the fantasy of marrying one of your idols?

Savannah is an aspiring author, working as an assistant at a literary agency in NYC. There, she meets a well-acclaimed horror novelist, Bennett Bryson, who is nothing short of dreamy, successful and sweet. They begin a whirlwind romance that quickly ties up in a marriage and Savannah drops everything to move into his country-estate up in upstate NY. Everything about Bennett is desirable and Savannah adores and admires him...but everything that appears good quickly turns threatening.

The house she moved into? Is like a shrine of his dead ex wife Poppy. His work room? completely off limits to her! Their relationship? Turns controlling as he begins to dictate all her daily life activities. She asks him to look at her written work? Well, he MOCKS her writing, discrediting and criticizing every word.

What happened to the charming man she met??

And THEN, she runs into a woman who tells her that Bennett killed her friend... what is Savannah going to do??

...but thats NOT all.

Savannah is... read to find out!

I loved the unreliable narrator and how suspicions were shifting between different POV's. As despicable and narcissistic the male lead was, Constantine written him so well. His behavior was suspicious from the very start. There was something dangerous and secretive about him and he was a great threat. But Constantine then complicated the familiar formula with a jaw dropping revelation, once again shifting everyones motives...let me tell you, the shock value was strong. This had all the sauce but the story was overall outlandish. I must admit some parts were far fetched but if you're looking for a fun, popcorn thriller, look no further!





Many thanks to NetGalley, Ballantine and the author, Liv Constantine for an early ARC!

3.5 rounded up to a 4

This was definitely a fast, easy read—which was exactly what I needed right now! 🙌 The writing was smooth, the story was easy to follow, and I flew through it pretty quickly.

The beginning was a little slow for me, and you definitely have to suspend some disbelief at times (because really… ONE MONTH?! 😵‍💫😵‍💫), but once things got going, I was invested.

The culprit was pretty easy to figure out, but there were still some good twists toward the end that helped wrap everything up nicely. Overall, a fun, low-effort mystery that was perfect for my current reading mood!

Thank you to Net Galley and Ballantine Books for giving me this ARC in exchange for my honest review.

Talk about a killer twist!! if you want a fast paced read that will consume your mind Liv Constantine is the author you need. She always delivers on shady characters, jaw dropping twists and a story that is never predictable. I absolutely devoured Promise Me Never, it was so addictive and so fun to read.

And what is even more fun is that it is about a writer and an aspiring author who get married after a whirlwind romance. Bennett Bryson has been here before, and the more his new bride Savannah learns about his past the more she realises that she can’t trust him. Oh, and there is a dog which always wins me over.

Thank you to Ballantine on NetGalley for my early copy of this book by a much loved author. Out on August 18th.

Thank you so much to NetGalley, Ballatine, and Liv Constantine for the ARC.


Savannah, an aspiring writer meets Bennett Bryson, a horror novelist. The two have a whirlwind romance - which later spirals when Savannah realizes that Bennett is who he isn’t appearing to be.


I went in blind with only the premise and once I got deeper into reading, I was hooked.


Unlike most domestic thrillers, this one’s told in third person with alternating chapters between Savannah, Bennett, and Poppy. It took a minute to adjust, but the perspective shifts added depth and character development.


The character I liked the most was Poppy, she was artistic and her chapters were my favorite to read. Savannah, as the female lead, felt underdeveloped. I wasn’t a fan of Bennett either. He was fine at first, but during the course of the book, his character did a complete 360.


A domestic thriller like this hit the nail on the head. This is perfect for anyone who enjoys unreliable narrators you fully can't trust.

⭐⭐⭐

Promise Me Never centers around an aspiring writer named Savannah, who has her ultimate dream come true when she marries her literary idol, bestselling horror author Bennett Bryson. Unfortunately, the man behind the books is far more frightening than anything he's ever written, and Savannah soon finds herself questioning everything she knows about Bennett—and the disturbing secrets surrounding his first wife.

This felt like vintage Liv Constantine: secrets, lies, questionable decisions, and enough twists and turns to keep me turning pages long past when I should have stopped. Promise Me Never is very much a popcorn thriller, and honestly, sometimes that’s exactly what you want. There was always something happening, and just when I thought I had things figured out, Constantine would throw another twist into the mix.

My biggest issue, though, was that eventually the twists became a little too much for me. The story ventures so far into the realm of the unbelievable that I found myself struggling to suspend my disbelief. There were definitely moments where I could feel myself thinking, Okay…are we really doing this? 😂 And sadly, once I started questioning the plausibility of the plot, it became harder to fully immerse myself in it.

I also felt like the writing itself was a little less sophisticated than what I've come to expect from Constantine. Certain aspects felt more elementary and straightforward, which made this read somewhat differently from some of her earlier releases. That said, none of that stopped me from being entertained. This book moves, and there was never a dull moment. I flew through it largely because I needed to know what ridiculous twist was coming next!

Ultimately, Promise Me Never was a fun, twisty, highly entertaining thriller that just didn't quite live up to the standard Constantine has set with some of her previous books. I enjoyed the ride, even if I didn't always believe the road we were traveling down. 😅

Entertaining? Absolutely.
Bingeable? Definitely.
Believable? Ehhh…not so much.

Still, if you're looking for a fast-paced popcorn thriller packed with secrets and twist after twist, this one certainly delivers.

I went into this quite excited, the premise immediately caught my attention, and the novel opens with enough intrigue to make you feel that you’re stepping into a story filled with secrets waiting to unravel.

However, as the narrative progressed, I found myself losing a bit of footing in the middle section. The story begins with promise, but for a considerable stretch not much of consequence seemed to occur until well over twenty chapters in, which slowed the momentum more than I expected and by the time the twists arrived toward the end, they appeared rather suddenly. A few of the reveals felt rushed and quite honestly, slightly less impactful than they might have been with more space to develop.

Character-wise, I struggled to form a strong connection with the characters though Savannah stood out as the perspective I found the most engaging.

All that being said, I did appreciate the structural choices in the storytelling. The use of multiple POVs and dual timelines is a creative approach that gradually pieces things together and helps to build tension.

Overall, the concept behind this story is genuinely interesting and clearly has strong potential. For me, the execution felt somewhat uneven, though I can certainly see how the premise and layered narrative style may appeal to many readers. Perhaps I’m simply the outlier here, but this one didn’t quite land for me in the way I had hoped.

Huge thanks to Ballantine Books and Netgalley for providing me with an advance copy in exchange for an honest review.

the setup…
Savannah is the assistant of hire-powered New York book agent Marion Sutton who also represents bestselling horror novelist Bennett Bryson. His debut novel Promise Me Never was a bestselling hit he’s also Savannah’s idol. She joins him and Marion for dinner and he becomes instantly smitten with her. A few weeks later, the two are married and she’s moved into his upstate Bedford estate. Savannah is also writing an book and Bennett helps provide critical input. Wedding bliss soon starts to lose its shine when his controlling nature emerges. He tries to dictate her every move and his feedback on her book now feels mean. When Savannah learns he not only was married before to Poppy but she died mysteriously, she begins to worry for her own safety. That becomes magnified after she receives anonymous warnings. Is Bennett writing from experience and why isn’t she allowed in his office?

the heart of the story…
I liked having three points of view from Savannah, Bennett and Poppy (from the past). All of them seemed to be harboring secrets that were slowly revealed as the story progressed. It got twisty early on, which I’d anticipated but still wasn’t quite prepared for some of the shockwaves.

the narration…
I was in listening heaven with Suzanne Elise Freeman, Stephanie Németh-Parker, Scott Brick & Alex McKenna. Brick kept me off balance with Bennett as did Freeman and Németh-Parker with Poppy and Savannah. This was special.

the bottom line…
And the twists just kept on coming along with a host of suspicious characters, including Savannah & Bennett. I started patching together a pretty good theory and nailed some of it but missed a big twist. I had a good time with the story until it started to fall apart for me somewhat at the end. Still, this was just the popcorn thriller I’d anticipated even with a hole or two as I finished it in one sitting. 3.5 stars

Was the AI portion mentioned in the book supposed to be a dig towards someone? Hmmm 🤔😏

“Promise Me Never” hooked me from page one and left me reeling by the end. I was cruising at four stars, enjoying the simmering tension, when Liv Constantine hit me with a finale so wild that I instantly bumped it up to five stars.

Thanks to the author and Bantam Books for the eARC received via NetGalley. All opinions are my own and left voluntarily.

Savannah is desperate to publish her debut novel and just as desperate to catch the eye of horror superstar Bennett Bryson. When she finally does, their whirlwind romance feels almost too good to be true. Engagement comes quickly, with Savannah swept off her feet and into Bennett’s remote, lavish estate.

But the fairy tale crumbles fast. Bennett’s charm sharpens, and his critiques of Savannah’s writing turn controlling. She tries to convince herself he’s just being a tough mentor, but the house’s isolation, his constant monitoring, and the subtle pressure he applies make the atmosphere increasingly claustrophobic.

Savannah knew about Bennett’s first wife’s tragic boating accident, but she soon uncovers a pattern: other women in his life ended up suspiciously dead. The deeper she digs, the more it feels like she’s living inside one of his sinister stories. Watching Savannah shift from dazzled fan to a woman fighting for her life is where this book really bites.

Constantine layers on the psychological tension and uses the setting masterfully. The estate is practically a character itself, amplifying Savannah’s fear. The novel digs into ambition, manipulation, and the danger of confusing charisma with decency. Savannah’s journey isn’t just about survival, but about finding her own voice.

And that ending? It’s the kind that makes you sit back and mutter “holy moly” to yourself. Satisfying, gutsy, and the sort of twist that made me want to rethink every page.

Promise Me Never
By: Liv Constantine
Pub Date: August 18, 2026
Publisher: Bantam

This sister author team is back with a suspenseful thriller and I am here for it.

We find Savannah who is wanting to be an author. She makes it her mission to meet novelist Bennett Bryson, who writes horror. Bennett is charming and pulls Savannah into his web with a quick romance that leads to marriage.

Bennett has a dark side and soon Savannah will discover who “he” really is. She is living in his home and is haunted by his first wife Poppy. She died in an accident.

Without any spoilers, get ready to put life on hold and buckle up for one crazy ride. Be careful what you wish for!

Review of advance copy received from NetGalley

Blackbeard meets Rebecca is a very good definition for this story. It's a little wild, a little out there, but most of all, if you go into this one just expecting a good time, you won't be disappointed.
Is it literary genius? No. Is it well plotted out and keeps you guessing? Also, not really, but it is a captivating story nonetheless that I breezed through in no time and had no complaints about. It was a fun summer read I don't regret reading at all and one I would definitely recommend.
