Description
The escapist crime thriller for fans of Below Deck, Lucy Clarke and T.M. Logan
WHEN THERE'S BLOOD IN THE WATER, A FEEDING FRENZY IS SURE TO FOLLOW . . .
The Ophelia is your typical superyacht: luxurious, owned by a ruthless billionaire and staffed by crew who have just one job: keep the guests happy, whatever it takes. Sasha is the latest hire on a week-long Atlantic crossing, and she fits right in. In fact, she could be mistaken for any of the stewardesses: tall, blonde and model gorgeous.
But despite its sleek opulence, the Ophelia isn’t as heavenly as it seems. And when one of the stewardesses is found dead after a night of partying, all eyes turn to Sasha. But she’s not the only one with something to hide and below deck, nothing stays hidden for long.
Endlessly twisty and delightfully voyeuristic, I Did Warn Her is a whodunnit on the high seas, where the dark secrets of the ultra-wealthy have nowhere to hide.

Oh my gosh, I literally was up all night reading this. It was so worth the lack of sleep! I could not force myself to stop I wish I could go back and force myself to slow down, re-read it and savour every moment. I loved it!
This plot had me hook, line and sinker! One of the most gripping, unputdownable, nerve-wracking books that I have EVER read!!! It had me on the edge of my seat throughout!
I’d recommend clearing your schedule before you start it as I read this in one sitting as I could not put it down! I loved the concept and the plot basically everything about it!
⭐⭐⭐⭐⭐ stars!

I absolutely loved this book! From start to finish, it was a gripping read with a perfect blend of thriller elements and the drama of Below Deck. The fast-paced storytelling kept me hooked, and the mystery element was woven in so well that I was constantly trying to piece everything together.
One of the strongest aspects of the book was its characters. Each one had real depth, and their development throughout the story made them feel incredibly lifelike. At first, I found it a bit challenging to keep up with the multiple POVs, but once I got to know the characters better, following their perspectives became much easier—and even more enjoyable.
The ending was everything I wanted and more. It wrapped up the mystery in a way that was both satisfying and surprising. I couldn’t put the book down and would absolutely recommend it to anyone who loves a fast-paced thriller with well-developed characters. A solid 5-star read!

Another great read from Sian Gilbert.
Such a twisty story, that kept me turning those pages, wanting to know what would happen next.
With great characters some I loved some I disliked, but they all brought something special to the story.
Thank you NetGalley and Penguin Random House UK for the ARC

Thoroughly enjoyable. I'm a huge fan of this author, her first novel She Started It is one I still think about now, long after reading it. And I'm positive I Did Warn Her will stay with me too. I enjoyed the ocean setting and the unique characters, and the storyline is a complete rollercoaster, absolutely jam packed with shocking twists

Glitzy Whodunit…
The Ophelia - a luxury super yacht with a, perhaps, ominous title - has every single amenity. Owned by a billionaire, fully staffed with a crew who are there to keep guests happy and content. Sasha is the latest recruit, last minute, for the next week long crossing. On her arrival she is perturbed to note that every single stewardess looks exactly like her. To onlookers, the super yacht is the height of hedonism - but something heinous lurks and when a body is discovered, secrets and lies may out. Glamorous and glitzy whodunit in the world of the super rich where nothing is quite as it first appears with a deftly drawn and credible cast of characters populating a pacy and menacing plot. Dark and compelling.
