Thank you NetGalley and publisher for this book!

What a good book! I really enjoyed this book and had such a hard time putting it down. I enjoyed the writing style. The characters worked so well together and the plot was great.

This was a 4 star read for me! I never saw the twist coming and I love the whodunnit vibe of it with everyone onboard having something to hide. The setting was great. Overall very good book

This is fun mystery book. The mysterious passing of a previous stewardess and the disappearance of expensive jewelry create an atmosphere of distrust that intensifies with each passing day. The plot thickens as the yacht's ruthless owner brings more beautiful and secretive guests on board, adding to the intrigue. The dynamic between the crew and the guests is masterfully portrayed, with everyone hiding something and suspicion mounting. The author keeps readers on edge, weaving a narrative filled with twists and turns that make it impossible to put the book down. The sense of isolation on the open sea heightens the tension, making every interaction fraught with potential danger.

What sets this book apart from other similar books is its delightfully voyeuristic look into the lives of the ultra-wealthy and the dark secrets they harbor. The writing is sharp, the characters are well-developed, and the pacing is perfect. This one kept me guessing until the end.

This book is a must-read for fans of suspenseful mysteries and anyone looking for a gripping tale of deception and intrigue on the high seas.

An entertaining locked room Cruise mystery. Perfect for fans of escapist vacation type thrillers. Those who loved She Started It will not be disappointed

Thank you to NetGalley and William Morrow for a free eARC of this awesome book!

Let me start by saying that I am a HUGE fan of Bravo’s “Below Deck”, so when I saw this pop up on NetGalley and read the synopsis, I knew I had to request it!

The superyacht Ophelia is getting ready for its final charter of the season. One of the stewardesses was dismissed right before this last charter, so she is replaced by Sasha. Sasha used to be a nurse, and something has caused her to leave that profession and join the crew of this ship. As soon as she boards, she sees they all of the other stewardesses look exactly like her. Everyone has an attitude, and there has been an entire charter season worth of drama building up. Sasha starts questioning her decision fairly quickly.

The guests for the final charter are two scumbags, and their escorts. These guys are real sleazy, and only want one thing from women. One of the escorts has a past that is tied to the Ophelia…a past that she is trying to piece together to find out what happened to her best friend, a stewardess on the ship last year.

I won’t say any more than that. There were so many chapter cliffhangers in this, and it annoyed me because I just couldn’t put it down! Very twisty. Very satisfying. Very dramatic. It’s like an episode of “Below Deck” with some added murder! Definitely check those one out!

This mystery was engaging at first from the beginning with the instant introduction to the dead body. Multiple POVs weren't really needed as the mystery kept going on and on almost in circles as the side characters became useless. The ending wasn't as satisfying but the epilogue did leave the door open to a potential spin off with the actual murderer.

3.5 stars - Someone is murdered on a luxury yacht while out in the middle of the ocean. The killer is among the guests or crew and no one can leave.

I love a locked room mystery and this book executed it well. I was thoroughly entertained the entire time. There are a lot of characters and multiple chapter POVs which was a bit confusing at first. Despite multiple plot twists, I didn’t feel satisfied when they were revealed.

If you’re a fan of Mean Girls and Below Deck, you’ll enjoy I Did Warn Her.

Thank you to NetGalley and William Morrow for providing me with an advance reader copy in exchange for an honest review.

I received an advanced copy of this book from William Morrow via NetGalley.

Luxury yachts, scandalous secrets, and a touch of murder—what could go wrong? The Ophelia dives into the glittering, treacherous world of mega-yachts, where the champagne flows endlessly, the jewelry keeps disappearing, and murder might just be on the itinerary.

The story follows Sasha, the newest addition to the yacht’s all-blonde, model-perfect crew of stewardesses, as she embarks on a weeklong Atlantic crossing with a group of wealthy, enigmatic guests. The Ophelia might ooze opulence, but the luxury veneer quickly cracks when whispers of a mysterious death, missing jewels, and mounting tensions among the crew start to bubble to the surface. When a crew member turns up dead after a night of debauchery, the yacht becomes a floating pressure cooker of suspicion. Everyone aboard—crew and guests alike—has secrets to hide, and with no land in sight, there’s nowhere to run.

The premise is killer (pun intended): murder on a billionaire’s mega-yacht? Sign me up. The setting is dripping with potential, offering the perfect storm of isolation, wealth, and interpersonal drama. And while fans of Below Deck will recognize the references and dynamics of high-stakes yacht life, some gaps in authenticity might leave insiders scratching their heads. (Seriously, five stewardesses but only three deckhands? Even the real Captain Sandy would raise an eyebrow.)

The pacing is quick, and the drama unfolds steadily, but the story falters where it should shine: the characters. The crew and guests feel underdeveloped, and with so many “model-gorgeous” blondes running around, it’s hard to tell who’s who—let alone care who’s hiding what.

Still, The Ophelia is a fun, breezy read.

Felt like a lot of characters at times and sometimes got the characters mixed up. Funny I thought of "Below Deck" immediately when I started reading and then read that the author mentions it. Overall, the book was just ok for me. It was nothing truly special.

I love a locked room mystery and being on a ship while doing that is terrifying. It had that tension that I was looking for and enjoyed getting to know the characters. I was invested in what was happening and thought the overall feel worked well overall. Sian Gilbert has a great writing style and I enjoyed the previous book in the series.

A very fun locked-room mystery at sea!

The beginning was a bittttt over the top with all the drama between stewardesses, but soon as the first murder occurs, things kick off and I really enjoyed it. Very quick read, would recommend for lovers of multi-pov mysteries where everyone's a suspect!

Thanks to Netgalley and the publisher for the arc!

A luxurious yacht sets sail to New York, hosting two business moguls—including the yacht's owner—and their glamorous companions. The crew comprises stunning, model-like blondes, indistinguishable from one another, as if they were Margot Robbie’s doubles from Barbie. Head stewardess Jade is determined to ensure everything runs smoothly—no mishaps like last year when an "accident" cost them a stewardess. Keep your cool, smile, and move on, right?

Young Sasha, fresh from quitting her nursing job under suspicious circumstances, joins the crew for a weeklong Atlantic crossing. She's hired not for her experience but her striking looks and blonde hair, perfectly matching her fellow stewardesses. Jade is a perfectionist, driven and callous. Imogen, the sharp-tongued, vengeful stewardess, targets Sasha, accusing her of stealing Alex—the handsome bosun who might be sleeping with everyone behind Imogen’s back. Effie, the narcissistic, ex-model, feigns friendliness while plotting others’ downfalls. Then there’s Lola, the youngest crew member, a spoiled rich girl disowned by her family. Though labeled naïve, she knows more about the yacht’s secrets than anyone suspects.

The yacht owner brings his best friend and two special guests, Eva and Jasmine. Jasmine, however, seems eerily familiar and pries into the events of last year. But soon, bigger problems arise: one of the stewardesses is murdered, and it’s just the beginning. Who’s targeting the crew? What schemes is the captain hiding? And who is erasing evidence to disguise murder as accidents? On this yacht, everyone has secrets, and no one is trustworthy. To survive, the stewardesses must unmask the killer—before they turn on each other.

OVERALL:
I had a great time with this book, especially laughing at Effie and Imogen’s POVs. Both were delightfully detestable, and I couldn’t decide which was worse. Normally, reading so many POVs featuring unlikable characters would make a story less enjoyable for me, but the author’s sarcastic tone and tightly woven mysteries kept me entertained. The nonstop action hooked me from the start, and the whirlwind of revelations made this an addictive read. I even shouted, Ship Ahoy! as I dove into this wild ride!

That said, the book’s length felt excessive, with numerous perspectives—including the five stewardesses and Jasmine, the enigmatic guest. I even wondered why Runa, the cook, didn’t get her own POV! The final chapters were packed with action and flash-forward scenes leading to a twisty epilogue, but I felt the biggest question readers had wasn’t fully addressed. Still, if you’re okay with a long read and juggling a large cast of flawed, chaotic characters, this book makes for a perfect popcorn mystery—thrilling, funny, and entertaining, much like the author’s previous work.

I’m rounding up my 3.5 stars to 4 and highly recommend it for fans of wild, action-packed journeys and delightfully messy characters!

This was a fun thriller to read! I loved that it reminded me of the Bravo show Below Deck if it went of the rails. I enjoyed the different perspectives and all of the details of the yacht and what was happening. There were some good twists and I wanted to keep reading to see what would happen. Lots of drama!

A luxurious yacht, a gorgeous crew with secrets and rivalries...and murder! I Did Warn Her is a cunning locked room mystery set on a billionaire’s yacht!! Good book!! This book had great suspense, fantastic mystery, murder, paid escorts, gaslighting, a great who done it and some wild twists! The story was very interesting! I definitely recommend reading this book! Thank you NetGalley and the publisher for sharing this book with me!

Thank you to NetGalley and HarperCollins William Marrow publishing for giving me the chance to read an advanced copy of this entertaining thriller.
This is the second book I've read by Sian Gilbert, and I've become a fan. The book takes place on a superyacht, which is a clever location for a thriller/mystery. The descriptions of the ship were detailed and almost a character itself. It is an expedition across the Atlantic to NY. As they travel, things keep going wrong and escalating into death.
The story is told through the perspectives of the multiple stewardesses, which is a similar style to Sian Gilbert's previous book. I'm usually not a fan of more than two perspectives, and it took maybe half of the book to finally be able to keep each name and character straight in my mind, but it helped add to the mystery. Everyone is keeping major secrets, and it was fun to not quite know who was involved in each crime and murder. There are a few characters who were decent, but most of them were complex and often cruel at times.
I enjoyed this thriller. It was fast-paced, not too graphic with violence, and it was hard to guess what would happen next. I'm looking forward to more books by this author.

I really enjoyed this book. I liked “She Started It” better but I think that’s just because I preferred the setting to the one in this book. The twists and turns were fun and the ending was very well set up.

Thank you to NetGalley and William Morrow for providing this book, with my honest review below.

I Did Warn Her swept me away to a mega yacht but had enough unlikeable characters that it was no vacation I’d want to take. I’d go as far as to say it had a few too many characters for me, though that did make this mystery multi layered. No one is who they appear to be on this yacht as almost all are hiding secrets (or too despicable to bother hiding them). Finding out what exactly was afoot, as in who murderer whom, past and present, was a great way to get me invested in the story and there were plenty of twists to have me thinking I may just want to pull out a white board to connect everyone and everything to try to unearth everything.

Though many of the characters inspired hatred at many points I do wish we had maybe two fewer to keep this a bit smoother. Still mission accomplished to Sian Gilbert as her first book knocked my socks off with its creativity and this one further proves she can weave a complex tale that readers are going to be hard pressed to try to spoil for themselves before she is ready to reveal all.

Easily a top ten read for me this year( and it’s not even close) this is the first book I’ve read by Sian Gilbert and I’m so impressed. I really enjoyed being able to experience this story from so many different perspectives. The ending?? Perfection. Just when I thought I had it figured out the epilogue twist blew me away! Everything I look for in a thriller and the location was so unique and different and I loved that aspect a lot!

"Below Deck" meets murder for sure! The flow between the different viewpoints was solid and I always knew who was talking and what they were referring to. The characters were well-rounded and there were no unnecessary details or plot lines. The story was engaging and kept me intrigued the entire time (I finished this in 2 days!). Highly entertaining.

Thank you netgalley and the publishers or this ARC of this book. This was a thriller that had me hooked with plot twists that I didn’t see coming. The character development was what hooked me, and the story’s plot kept me engaged. The pacing and themes throughout the story were well developed and I definitely will be recommending this to my book club in 2025.
