My Review
My Every Assumption Was Wrong

I was constantly trying to piece things together — and constantly getting it wrong. This is a story that thrives on uncertainty, and I was completely caught up in it almost immediately. There’s a quiet, creeping tension running through the book that never really lets up, lingering in the background even during calmer moments.
From early on, I felt slightly unsettled, as though the ground beneath the story was never quite solid. I was always questioning what I was being shown, wondering whether I was missing something important or drawing the wrong conclusions. That sense of doubt became a defining part of the reading experience, and rather than frustrating me, it pulled me in deeper.
The structure of the book plays a huge role in this. The shifts between timelines and perspectives kept me off-balance throughout, and while I did find this a little confusing at first, it soon became clear that this was entirely intentional. Once I found my footing, I realised how effectively this approach heightened the suspense and reinforced the themes of uncertainty and mistrust. I even found myself flicking back and making notes, not because I felt lost, but because I was so invested in trying to connect all the threads.
What really impressed me was how layered the story felt. Each new section added another possibility, another angle to consider, another reason to doubt what I thought I understood. Just when I felt close to putting the pieces together, the narrative would subtly shift and send me back to reassess everything that came before. That constant recalibration kept the tension high and made the reading experience incredibly immersive.
The atmosphere is heavy and intense without being overwhelming. The scene-setting is vivid and carefully controlled, creating a strong sense of place and mood that lingered with me long after I put the book down. There’s a steady, underlying sense that something isn’t quite right, and it never fully releases its grip.
This was my third book by Sadie Ryan, and once again she delivered exactly the kind of reading experience I love: clever, unsettling, and psychologically tense. I finished the book feeling genuinely impressed by how tightly everything was woven together, and how confidently the story trusted the reader to sit with discomfort and doubt. I won’t hesitate to pick up anything she writes in the future — she’s firmly earned her place on my auto-read list.
