For me, a very average thriller. I liked the concept and the opening chapters were gripping, but about 30% in it really began to lose its way. The relationship between the protagonist and the ex felt stale (I couldn’t fathom why it was meant to be such an earth-shattering unforgettable first love), the husband was basically forgotten about, the brother disposable, and I got very tired of the protagonist repeating herself over and over again. A couple of good twists, but if you’re an avid thriller reader you will have seen them coming a mile away. A decent page-turning read, but not the best considering the hype.
