It's literally my favorite thriller book so far! THE PLOT TWIST!!!! I did not see it coming at all. I've never felt this way about any other character like I did with Cora—I genuinely loved, hated, admired, and got pissed at her throughout the whole book. And Margo, oh my god, I loved her so much. I felt peace whenever I read her POV, but I was also anxious because something could always happen. She’s worried all the time, and she made me worried too.

I've never felt so many active emotions while reading a book. My heart ached during that scene where Ralff passed a note to Margo in class. I felt her pain and her invisibility. As someone with two sisters close to my age, my biggest nightmare is being seen as competition to each other, and this book touched me deeply.

There were no plot holes whatsoever—it all made so much sense in the end. Not that it didn’t as I was reading, but looking back, I’m like, OOHHHH. When Cora signed a note with the same nickname as their old nanny's sister, it itched my brain in the best way, and the switch of POVs near the end between the twins when "they" went to talk to the therapist UGH. I LOVE THISSSS. PLEASE READ IT!
