The Break-up Retreat

Camilla Sten

Suspense, Mystery, Thriller • Jun 9, 2026

The Himlafall Clinic promises a revolutionary cure for heartbreak deep within the Swedish woods. But for Isobel Andersen, the retreat isn't a place of healing—it’s a crime scene. Investigating rumors of women who check in but never check out, Isobel goes undercover to expose the clinic's founder, Dr. Martina Hastings.

3.5 / 5

The Himlafall Clinic makes for a chilling backdrop in The Breakup Retreat, and the atmosphere is exactly what you'd expect from a Camilla Sten mystery. The story stays in Isobel’s perspective, but the addition of Martina’s social media posts and some Reddit threads keeps the mystery of the clinic engaging. Those digital snippets provide a modern layer to the plot that makes it easy to stay invested in what is actually going on.
The short chapters also make this a very quick read, which is always a plus for keeping the momentum high in a thriller. While Isobel is a decent lead, the subplot involving her father felt unnecessary and didn't really add anything to the story. The twist itself is quite interesting, though some of the ways things play out near the end feel a bit juvenile and silly. It isn't a perfect thriller, but it is a solid, enjoyable read. #TheBreakUpRetreat #NetGalley
