As soon as I read the synopsis, I wanted to read this book. And as soon as I started reading it, I was gripped. It's just such a unique plot, completely unlike anything I've ever read before, and one of those books where as soon as you think you've got a handle on what's going on, everything twists and changes and you're thrown right back to the start of trying to work it all out!
Plot wise, I won't comment, as there's a lot of potential for accidental spoilers. But what I will say is that Sarah is a fantastic character to read about, as she's just so unreliable, and right from the start you're questioning whether her take on things is trustworthy or not. The relationship between Sarah and her twin Evie was also really well written, portraying both the positives and negatives of having such an intertwined relationship.
Now, there were some issues with pacing, whereby some sections were very fast-paced and kept your interest, whereas others were a bit slower and a tad repetitive, so that is something to keep in mind. And as with most thrillers, some sections did seem a bit far-fetched. But that's me being fussy, as I personally don't mind my books a bit unrealistic - it is fiction after all! So all in all, a really unique and enjoyable read, and a welcome addition to my growing collection of psychological thrillers.
