“I Did Warn Her” by Sian Gilbert is a slick, unsettling, and utterly bingeable thriller that had me hooked from the first page. What starts off as a glamorous getaway quickly spirals into something darker and more dangerous, and I couldn’t turn the pages fast enough.

This story cleverly plays with the idea of toxic friendships, ambition, and secrets kept just under the surface—until they explode. The structure alternates timelines and perspectives in a way that’s addictive without being confusing, and each new revelation lands with a sharp, satisfying twist. Just when I thought I had the story figured out, Sian Gilbert pulled the rug out from under me again.

The atmosphere was particularly well done—claustrophobic, luxurious, and ominous. It captured that perfect blend of sun-soaked beauty and undercurrents of menace, making it impossible to relax, even during the “fun” moments. And the social commentary? Spot on. There’s a lot being said here about privilege, power, and performative behavior, all wrapped in a fast-paced thriller.

The only reason this wasn’t a full five stars is that I wanted just a bit more from the ending—it landed well but left a few things slightly open-ended for my taste. Still, it’s a strong, smart, and satisfying read overall.

Huge thanks to NetGalley and William Morrow for the opportunity to read this early. I’ll definitely be recommending this one to fans of Ruth Ware, Lucy Foley, or anyone who loves a sun-drenched thriller with bite.
