I was honestly really loving this book, and the ending definitely made me cry, but I didn't love it. The twist felt a little cheap and rushed. Though I totally understand it as an ending, and how it brings things full circle, I just personally didn't enjoy that. It might click with someone else. Still, I loved the characters and the concept and the very ethical question it brings up, and especially how we can relate it to topics like abortion in today's society. I also adored how we jumped between points of view, but never really saw Kate's until the end. It's interesting what you can extrapolate from that, and how Anna feels about her ignored perspective.
