There's a lot of whys and hows popping in my head while reading it. The plot is very intriguing, filling the reader's mind with curiousity. The twisted ending is also satisfying.
I wouldn't say I recommend this book, but if you're into psychological thrillers, then yes, this book should be on your to-read list. Frankly, for me, it wasn't a light read nor was it an easy read. I had certain moments of confusion. However, there was something to the story that lured me; like a siren calling out to their prey. And I agree that it is an extraordinary piece that deserves attention.
